Code Issues Proposed changes

Disable 'supports_migrate_to_same_host' HyperV driver capability 

The Hyper-V driver incorrectly enables the
'supports_migrate_to_same_host' capability.

This capability seems to have been introduced having the VMWare
cluster architecture in mind, but it leads to unintended behavior
in case of the HyperV driver.

For this reason, the Hyper-V CI is failing on an recently introduced
tempest test, which asserts that the host has changed.

This change disables this driver capability.

fixes:
- The Hyper-V driver no longer accepts cold migrating
instances to the same host. Note that this does not
apply to resizes, in which case this is still allowed.
