Add APIMicroversionFixture to library interface

Browse Source 
APIMicroversionFixture is used to set the microversion on
service clients which will take care of reseting the microversion.

This interface has been added to set the microversion on all supported
service clients which use microverison. User can set multiple
service microversion all together.

Using the new interface in compute tests to make sure it is all
working in serial and parallel testing.

New library interface to set the API microversion on Service Clients.
``APIMicroversionFixture,`` can be used to set the API microversion
on multiple services. This Fixture will take care of reseting the service
microversion to None once test is finished.

"""API Microversion Fixture to set service microversion.
This class provides the fixture to set and reset the microversion
on service client. Service client has global variable to set the
microversion for that service API request.
For example: base_compute_client.COMPUTE_MICROVERSION
Global variable is always risky to set directly which can affect the
other test's API request also. This class provides a way to reset the
service microversion once test finish the API request.
This class can be used with useFixture: Example::
def setUp(self):
super(BaseV2ComputeTest, self).setUp()
self.useFixture(api_microversion_fixture.APIMicroversionFixture(
compute_microversion=self.compute_request_microversion))
Or you can set microversion on multiple services together::
def setUp(self):
super(ScenarioTest, self).setUp()
self.useFixture(api_microversion_fixture.APIMicroversionFixture(
compute_microversion=self.compute_request_microversion,
volume_microversion=self.volume_request_microversion))
Current supported services:
- Compute
- Volume
- Placement
:param str compute_microversion: microvesion to be set on compute
service clients
:param str volume_microversion: microvesion to be set on volume
service clients
:param str placement_microversion: microvesion to be set on placement
service clients
