            Get a connection from the pool and perform an HTTP request. This is the
            lowest level call for making a request, so you'll need to specify all
            the raw details.
    
            .. note::
    
               More commonly, it's appropriate to use a convenience method provided
               by :class:`.RequestMethods`, such as :meth:`request`.
    
            .. note::
    
               `release_conn` will only behave as expected if
               `preload_content=False` because we want to make
               `preload_content=False` the default behaviour someday soon without
               breaking backwards compatibility.
    
            :param method:
                HTTP request method (such as GET, POST, PUT, etc.)
    
            :param body:
                Data to send in the request body (useful for creating
                POST requests, see HTTPConnectionPool.post_url for
                more convenience).
    
            :param headers:
                Dictionary of custom headers to send, such as User-Agent,
                If-None-Match, etc. If None, pool headers are used. If provided,
                these headers completely replace any pool-specific headers.
    
            :param retries:
                Configure the number of retries to allow before raising a
                :class:`~urllib3.exceptions.MaxRetryError` exception.
    
                Pass ``None`` to retry until you receive a response. Pass a
                :class:`~urllib3.util.retry.Retry` object for fine-grained control
                over different types of retries.
                Pass an integer number to retry connection errors that many times,
                but no other types of errors. Pass zero to never retry.
    
                If ``False``, then retries are disabled and any exception is raised
                immediately. Also, instead of raising a MaxRetryError on redirects,
                the redirect response will be returned.
    
            :type retries: :class:`~urllib3.util.retry.Retry`, False, or an int.
    
            :param redirect:
                If True, automatically handle redirects (status codes 301, 302,
                303, 307, 308). Each redirect counts as a retry. Disabling retries
                will disable redirect, too.
    
            :param assert_same_host:
                If ``True``, will make sure that the host of the pool requests is
                consistent else will raise HostChangedError. When False, you can
                use the pool on an HTTP proxy and request foreign hosts.
    
            :param timeout:
                If specified, overrides the default timeout for this one
                request. It may be a float (in seconds) or an instance of
                :class:`urllib3.util.Timeout`.
    
            :param pool_timeout:
                If set and the pool is set to block=True, then this method will
                block for ``pool_timeout`` seconds and raise EmptyPoolError if no
                connection is available within the time period.
    
            :param release_conn:
                If False, then the urlopen call will not release the connection
                back into the pool once a response is received (but will release if
                you read the entire contents of the response such as when
                `preload_content=True`). This is useful if you're not preloading
                the response's content immediately. You will need to call
                ``r.release_conn()`` on the response ``r`` to return the connection
                back into the pool. If None, it takes the value of
                ``response_kw.get('preload_content', True)``.
    
            :param chunked:
                If True, urllib3 will send the body using chunked transfer
                encoding. Otherwise, urllib3 will send the body using the standard
                content-length form. Defaults to False.
    
            :param int body_pos:
                Position to seek to in file-like body in the event of a retry or
                redirect. Typically this won't need to be set because urllib3 will
                auto-populate the value when needed.
    
            :param \\**response_kw:

               More commonly, it's appropriate to use a convenience method provided
               by :class:`.RequestMethods`, such as :meth:`request`.

               `preload_content=False` because we want to make
               `preload_content=False` the default behaviour someday soon without
               breaking backwards compatibility.

                Data to send in the request body (useful for creating
                POST requests, see HTTPConnectionPool.post_url for
                more convenience).
    
            :param headers:
                Dictionary of custom headers to send, such as User-Agent,
                If-None-Match, etc. If None, pool headers are used. If provided,
                these headers completely replace any pool-specific headers.
    
            :param retries:
                Configure the number of retries to allow before raising a
                :class:`~urllib3.exceptions.MaxRetryError` exception.
    
                Pass ``None`` to retry until you receive a response. Pass a
                :class:`~urllib3.util.retry.Retry` object for fine-grained control
                over different types of retries.
                Pass an integer number to retry connection errors that many times,
                but no other types of errors. Pass zero to never retry.
    
                If ``False``, then retries are disabled and any exception is raised
                immediately. Also, instead of raising a MaxRetryError on redirects,
                the redirect response will be returned.
    
            :type retries: :class:`~urllib3.util.retry.Retry`, False, or an int.
    
            :param redirect:
                If True, automatically handle redirects (status codes 301, 302,
                303, 307, 308). Each redirect counts as a retry. Disabling retries
                will disable redirect, too.
    
            :param assert_same_host:
                If ``True``, will make sure that the host of the pool requests is
                consistent else will raise HostChangedError. When False, you can
                use the pool on an HTTP proxy and request foreign hosts.
    
            :param timeout:
                If specified, overrides the default timeout for this one
                request. It may be a float (in seconds) or an instance of
                :class:`urllib3.util.Timeout`.
    
            :param pool_timeout:
                If set and the pool is set to block=True, then this method will
                block for ``pool_timeout`` seconds and raise EmptyPoolError if no
                connection is available within the time period.
    
            :param release_conn:
                If False, then the urlopen call will not release the connection
                back into the pool once a response is received (but will release if
                you read the entire contents of the response such as when
                `preload_content=True`). This is useful if you're not preloading
                the response's content immediately. You will need to call
                ``r.release_conn()`` on the response ``r`` to return the connection
                back into the pool. If None, it takes the value of
                ``response_kw.get('preload_content', True)``.
    
            :param chunked:
                If True, urllib3 will send the body using chunked transfer
                encoding. Otherwise, urllib3 will send the body using the standard
                content-length form. Defaults to False.
    
            :param int body_pos:
                Position to seek to in file-like body in the event of a retry or
                redirect. Typically this won't need to be set because urllib3 will
                auto-populate the value when needed.
