Clinton Knight dddc068879 Add v2 Manila API path as base for microversions
To prevent a microversioned client from managing a non-microversioned
Manila server, Manila must update its REST endpoints by adding /v2 for
all microversioned APIs.

This commit does the following:

* Add /v2 to the URL map, connected to all the same /v1 API methods
* Renumber the microversion sequence starting from 2.0
* Update the versions API to reflect v2
* Publish the new endpoint to Keystone in the DevStack plug-in
* Update relevant documentation
* Update Tempest tests for microversions
