Code Issues Proposed changes

Add 'xenapi_apis' compute feature flag

Browse Source 
Nova is removing the XenAPI virt driver. There are a number of APIs that
only work with this virt driver so those are being removed at the same
time. Once removed, they will return a HTTP 410 response, regardless of
the microversion.

Add a feature flag that allows us to skip these tests on clouds that no
longer provide these APIs. It default to False (skip). We will set this
to True (do no skip) on stable branches of nova.

upgrade:
- |
A number of Compute APIs that only worked with the XenAPI virt driver have
been removed in the Compute service. As a result, their corresponding tests
are now disabled by default. They can be re-enabled using the new
``[compute_feature_enabled] xenapi_apis`` config option.
