326b3dace7 Make ObservableDeferred.observe() always return deferred. 
This makes it easier to use in an async/await world.

Also fixes a bug where cache descriptors would occaisonally return a raw
value rather than a deferred.

f44f1d2e83 Fix errors storing large retry intervals. 
We have set the max retry interval to a value larger than a postgres or
sqlite int can hold, which caused exceptions when updating the
destinations table.

To fix postgres we need to change the column to a bigint, and for sqlite
we lower the max interval to 2**62 (which is still incredibly long).

b74606ea22 Fix a bug with saml attribute maps. 
Fixes a bug where the default attribute maps were prioritised over
user-specified ones, resulting in incorrect mappings.

The problem is that if you call SPConfig.load() multiple times, it adds new
attribute mappers to a list. So by calling it with the default config first,
and then the user-specified config, we would always get the default mappers
before the user-specified mappers.

To solve this, let's merge the config dicts first, and then pass them to
SPConfig.

17e1e80726 Retry well-known lookup before expiry. 
This gives a bit of a grace period where we can attempt to refetch a
remote `well-known`, while still using the cached result if that fails.

Hopefully this will make the well-known resolution a bit more torelant
of failures, rather than it immediately treating failures as "no result"
and caching that for an hour.

Fix some error cases in the caching layer. (#5749) 
There was some inconsistent behaviour in the caching layer around how
exceptions were handled - particularly synchronously-thrown ones.

This seems to be most easily handled by pushing the creation of
ObservableDeferreds down from CacheDescriptor to the Cache.

Prevent multiple upgrades on the same room at once (#5051) 
Closes #4583

Does slightly less than #5045, which prevented a room from being upgraded multiple times, one after another. This PR still allows that, but just prevents two from happening at the same time.

Mostly just to mitigate the fact that servers are slow and it can take a moment for the room upgrade to actually complete. We don't want people sending another request to upgrade the room when really they just thought the first didn't go through.

Improve the logging when handling a federation transaction (#3904) 
Let's try to rationalise the logging that happens when we are processing an
incoming transaction, to make it easier to figure out what is going wrong when
they take ages. In particular:

- make everything start with a [room_id event_id] prefix
- make sure we log a warning when catching exceptions rather than just turning
  them into other, more cryptic, exceptions.
