network-interfaces: reload bridges on conf changes
And adopt the tests to add an interface and remove it again. It should work when deactivating rstp, it will not work when activating rstp for the first bridge as then the userspace daemon is not yet available. But once one bridge is active with stp, it should work with the reload for any further bridge. Fixes #21745. Also see #22547.
