    Make evacuate leave a record for the source compute host to process

    This makes the evacuate process leave a record in the database about the
    evacuation, and from what host it was being performed. Now, the compute
    manager will use that breadcrumb trail to decide whether it should delete
    locally-running instances, instead of just the hostname mismatch.

    Since this does a query by migration_type, I added a unit test to the
    test_db_api module to prove this actually works.

    DocImpact: Deprecates the workarounds/destroy_after_evacuate config option
