* Add service_name parameter in ::nova::api with unit testing covering
use cases.
* Add apache module to fixtures for unit testing.
* Add apache module to metadata.json.
* Add WSGI paths to ::nova::params.
* Create ::nova::wsgi::apache with unit testing covering use cases.
* Create acceptance tests to validate the transition from eventlet to
WSGI and make sure apache is stopped in eventlet testing.
* Create examples/nova_wsgi.pp to document use cases.
* Deprecate enabled_apis as a string, to be an array later (with unit
tests).
* Drop eventlet testing
Use-cases supported & limitations:
* All API (compute, metadata) running in eventlet and 100% backward
compatible.
This is a first implementation that keeps the deployment simple &
backward compatible.
During this cycle, we accept enabled_apis as a string, but in N cycle, we
will make sure it's an array so we can drop all the code that sanitize
the parameter to make sure we enable the right WSGI process.
