Bug Description

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 the test_cold_migration tempest test, which asserts that the host has changed.

    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.
