Write a program in asyncio, that calls into a library that knows nothing about asyncio, which then calls out to a database adapter that is only asyncio
"""Proof of concept of an adapter that will wrap a blocking IO library in
greenlets, so that it can be invoked by asyncio code and itself make calls out
to an asyncio database library.
hint: any Python ORM or database abstraction tool written against the DBAPI
could in theory allow asyncio round trips to a pure async DB driver like
asyncpg.
The approach here seems too simple to be true and I did not expect it to
collapse down to something this minimal, so it is very possible I am totally

mandatory

Basic Idea

The idea is to add another parameter to the function RPCCLient as:

client = oslo_messaging.RPCClient(transport, target, options={'mandatory': True})
client.call({}, 'foo', id_value=str(i), test_value="hello oslo")

Inside the function, _publish decode the option value, as:

export OS_PROJECT_DOMAIN_NAME='Default'
export OS_USER_DOMAIN_NAME='Default'
export OS_PROJECT_NAME='admin'
export OS_USERNAME='admin'
export OS_AUTH_URL=http://192.168.24.2:5000/
export OS_AUTH_TYPE='password'
export OS_IDENTITY_API_VERSION='3'
export OS_PASSWORD=$(sudo hiera -c /etc/puppet/hiera.yaml keystone::admin_password)
