Add possibility to run manila-api service under web servers that support WSGI applications

Registered by Valeriy Ponomaryov on 2017-03-22

One of the goals for Pike [1] is to make each API service be able to run under dedicated web servers such as Apache (+mod-wsgi) and Nginx (+uWSGI).

For the moment Manila uses only eventlet-based WSGI application approach for running all its services.

So, following goals defined in "governance" project [2] should be addressed in scope of this blueprint:

1) Provide WSGI application script file(s) (e.g. to be used by web server). There shouldn't be any web server restriction and the application could be deploying to any web server that support WSGI applications.

2) Switch devstack jobs to deploy control-plane API services in WSGI with Apache. Usage of Apache is already the default in Devstack, let's keep using it for consistency unless there is some efforts to support another web server but this is not the case at this time.
