Create the url_cache index on local_media_repository as a background update, so
that we can detect whether we are on sqlite or not and create a partial or
complete index accordingly.
To avoid running the cleanup job before we have built the index, add a bailout
which will defer the cleanup if the bg updates are still running.

via registration file "users" namespace:
```YAML
...
namespaces:
users:
- exclusive: true
regex: '.*luke.*'
group_id: '+all_the_lukes:hsdomain'
...
```
This is part of giving App Services their own groups for matching users. With this, ghost users will be given the appeareance that they are in a group and that they have publicised the fact, but _only_ from the perspective of the `get_publicised_groups_for_user` API.
wrap the call to _simple_upsert_txn in a loop so that we retry on an
integrityerror: this means we can avoid locking the table provided there is an
unique index.
... so that we don't need to secretly gut-wrench it for use in the slaved
stores. I haven't done the other stores yet, but we should. I'm tired of the
workers breaking every time we tweak the stores because I forgot to gut-wrench
the right method.
fixes https://github.com/matrix-org/synapse/issues/2655.
We're going to fix this properly on this branch, so that the _state_group_cache
can end up in StateGroupReadStore.
This reverts commit ab335edb023d66cd0be439e045b10ca104b73cb5.
I'm not entirely sure if this will actually help anything, but it simplifies
the code and might give further clues about why room list search requests are
blowing out the get_current_state_ids caches.
Add db_conn parameters to the `__init__` methods of the *Store classes, so that
they are all consistent, which makes the multiple inheritance work correctly
(and so that we can later extract mixins which can be used in the slavedstores)
If somebody sends us a request where the the body is invalid utf-8, we should
return a 400 rather than a 500. (json.loads throws a UnicodeError in this
situation)
We might as well catch all Exceptions here: it seems very unlikely that we
would get a request that *isn't caused by invalid json.
