Parameterize wsgi.py

gistfile1.txt

I recommend modfying wsgi.py for VMI/SMH/SMH_APP to enable some flexibility in the call to the EC2 parameter store. 

THe current code is:

###########################################
import os
from .ssmenv import EC2ParameterStore

from django.core.wsgi import get_wsgi_application

try:
    parameter_store = EC2ParameterStore(region_name="us-east-1")
    # Automate env (dev)
    django_parameters = parameter_store.get_parameters_by_path(
        '/dev/sharemyhealth/',
        strip_path=True)
    EC2ParameterStore.set_env(django_parameters)
except Exception:
    pass

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'sharemyhealth.settings')

application = get_wsgi_application()
###########################################

proposed revision:
###########################################
import os
from getenv import env
from .ssmenv import EC2ParameterStore

from django.core.wsgi import get_wsgi_application

AWS_DEFAULT_REGION = env('AWS_DEFAULT_REGION', 'us-east-1')
VPC_ENV = env('VPC_ENV', 'dev')
VPC_APP_NAME = env('VPC_APP_NAME', 'sharemyhealth')
PARAMETER_STORE_PATH = "/%s/%s/" % (VPC_ENV, VPC_APP_NAME)
# e.g. /staging/vmi, /prod/sharemyhealth, /dev/smh_app

try:
    parameter_store = EC2ParameterStore(region_name=AWS_DEFAULT_REGION)
    # Automate env (dev)
    django_parameters = parameter_store.get_parameters_by_path(
        PARAMETER_STORE_PATH,
        strip_path=True)
    EC2ParameterStore.set_env(django_parameters)
except Exception:
    pass

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'sharemyhealth.settings')

application = get_wsgi_application()
###########################################

This would allow a couple of environment variables to enable pulling of parameterstore variables based upon 
vpc environment and app name. Once code is stable it provides potential to change variables without 
rebuilding machines. Machine builds would then be limited to patching and code updates.
