The Host Maintenance strategy now supports two new input parameters:
``disable_live_migration`` and ``disable_cold_migration``. These
parameters allow cloud administrators to control whether live, cold or
no migration should be considered during host maintenance operations.
* If ``disable_live_migration`` is set, active instances will be cold
migrated if ``disable_cold_migration`` is not set, otherwise active
instances will be stopped.
* If ``disable_cold_migration`` is set, inactive instances will not be
cold migrated.
* If both are set, only stop actions will be applied on active instances.
A new `stop` action has been introduced and registered to support
scenarios where migration is disabled.
