Valeriy Ponomaryov 16bfc82962 Add possibility to run 'manila-api' with wsgi web servers
One of the goals for Pike [1] is to make each API service be able to
run under web servers that support WSGI applications,
such as Apache (+mod-wsgi) and Nginx (+uWSGI).

Do following to address governance requirements:
- Split existing manila/wsgi.py module into 3 modules:
  First (manila/wsgi/eventlet_server.py) is used by
  eventlet-based WSGI application approach.
  Second (manila/wsgi/wsgi.py) is used for WSGI web servers.
  And third (manila/wsgi/common.py) is common code for both.
  All three are made in cinder-like way to have alike-approach.
- Reuse common code from "oslo_service/wsgi.py" module that
  allows us to remove code duplication.
- Delete config opts that are defined by newly reused common code.
- Register new entry point that will be manila wsgi app: "manila-wsgi".
- Fix "manila/api/openstack/wsgi.py" module to be compatible
  with str/bytes handling approach used by Apache mod-wsgi plugin using
  different python versions (2/3).
- Add web server config template "devstack/apache-manila.template"
- Add devstack support where usage of this feature can be
  enabled or disabled using "MANILA_USE_MOD_WSGI" env var.
  It is set to "True" by default, because it is requirement for Pike
  release - to have it running in all CI jobs.
  Disable it only for one CI job that uses dummy driver and tests
  various manila core features that are not covered by other CI jobs.
