use `Failure()` to fish out the real exception.

It seems auth_events can be either a list or a tuple, depending on Things.

Fixes #2181. 

The basic premise is that, when we
fail to reject an invite via the remote server, we can generate our own
out-of-band leave event and persist it as an outlier, so that we have something
to send to the client.

... instead of duplicating `config.signing_key[0]` everywhere

This reverts commit e0c01296.

As discussed at
https://github.com/matrix-org/synapse/pull/7801#pullrequestreview-444652786, I
don't think this is an improvement.

* Starting with apt 1.6, https support has moved into the main package and apt-transport-https has become a transitional dummy package.

This table is no longer used, so we may as well stop populating it. Removing it
would prevent people rolling back to older releases of Synapse, so that can
happen in a future release.

* Add libwebp dependency to Dockerfile

* Fix spec compliance; tweaks without values are valid

(default to True, which is only concretely specified for
`highlight`, but it seems only reasonable to generalise)

* Changelog for 7766.

* Add documentation to `tweaks_for_actions`

May as well tidy up when I'm here.

* Add a test for `tweaks_for_actions`

Fixes https://github.com/matrix-org/synapse/issues/7641

The package was pinned to <0.8.0 without an obvious reasoning with
7ad1d763
in https://github.com/matrix-org/synapse/pull/5636


while the version selection looks to just try to exclude an arbitrary
next minor version number that might introduce API breaking changes.
Selecting the next minor number might be a good conservative selection.

Downstream distributions already reported success patching out the version
requirements.

This also fixes the integration of upgraded packages into openSUSE packages,
e.g. for openSUSE Tumbleweed which already ships prometheus_client >= 0.8 .

The CI appears to use the latest version of isort, which is a problem when isort gets a major version bump. Rather than try to pin the version, I've done the necessary to make isort5 happy with synapse.

fixes #7016
