In v2.1, os-hypervisors/servers API returns empty servers list in
case where hypervisors does not have any servers.
But this is not case with v2 API. v2 API does not put 'servers' field
in response if it is empty.
v2.1 APIs should be same as v2 in all cases/scenarios.
This is bug fix so not putting as microversions, its just a change to
the v2.1 code so it is equivalent to v2. If later needed then, this can
be reverted back as current ways via microversion.
This was no best test coverage to catch this kind of issue.
This was caught while merging the v2 and v2.1 tests
