ops 2.18.0 and ops-scenario 7.1.0

What's Changed

The Ops documentation has been dramatically revamped, with tutorials and how-to guides moved from Juju documentation to Ops where they belong, among with a myriad of other improvements.

The deferred event queue is now deduplicated, which should make charms feel more responsive.

Unit testing has been made faster by using an in-memory state database and a few other tricks.
