All python modules in "manilaclient/v1" override v2 modules with v2 modules
and v1 modules do not provide APIs at all. So, fix those imports and add
test coverage.

Closes-Bug: #1535692
The Manila client needs the following changes to support microversions:
* Maintain backwards compatibility with Kilo. When the client detects
that the server doesn't support microversions it will fall back to
using the v1 API.
* The --os-share-api-version option supports overriding the version.
* If 1.0 is specified as the version the client will load the v1
client and use the server's v1 API.
* The client will send a request for the server's API version and
determine if the client's supported versions and the server's
supported versions overlap. If not the client will display an error
and quit. See diagram 1 below.
* The client supports the @wraps annotation. The annotation is used
with the v2/shell.py commands and any class that inherits from
the Manager class in manilaclient/base.py.
* If an appropriate command version isn't found for commands using
@wraps then the client will display an error and quit.

Diagram 1:
Client:
2.5 2.8
|-------------|
Server1:
2.0 2.5
|-------------|
Client uses version 2.5
Server2:
2.7 2.10
|-------------|
Client uses version 2.8
Server3:
2.9 2.12
|-------------|
Client displays error and quits
Server4:
1.0 (Kilo Server)
|-|
Client detects pre-microversion server and loads v1 client
Example usage of wraps annotation:
* Support 2.0 - 2.4: @api_versions.wraps("2.0", "2.4")
* Support 2.5 - latest: @api_versions.wraps("2.5")
