neutron.tests.tempest.scenario.test_migration.NetworkMigrationFromHA.test_from_ha_to_dvr_ha [339.848078s] ... FAILED

The reason seems to be an inconsistency in these default config values:

enable_dvr = True
agent_mode = legacy

For consistency, either DVR should be disabled by default or the default
agent_mode should support DVR, so a default of dvr_snat would seem to be
the best solution.
