Some of the caches on worker processes were not being correctly invalidated
when a room's state was changed in a way that did not affect the membership
list of the room.

We need to make sure we send out cache invalidations even when no memberships
are changing.

Propagate opentracing contexts through EDUs

Propagate opentracing contexts across workers


Also includes some Convenience modifications to opentracing for servlets, notably:
- Add boolean to skip the whitelisting check on inject
  extract methods. - useful when injecting into carriers
  locally. Otherwise we'd always have to include our
  own servername and whitelist our servername
- start_active_span_from_request instead of header
- Add boolean to decide whether to extract context
  from a request to a servlet

This type of registration was probably never used. It only includes the
user name in the HMAC but not the password.

Shared secret registration is still available via
client/r0/admin/register.

Add opentracing tags and logs for e2e keys

There's no point doing a raise_from here, because the exception is always
logged at warn with no stacktrace in the caller. Instead, let's try to give
better messages to reduce confusion.

In particular, this means that we won't log 'Failed to connect to remote
server' when we don't even attempt to connect to the remote server due to
blacklisting.

These tables are never used, so we may as well drop them.

Hopefully, this will fix a stack overflow when recovering an appservice.

The recursion here leads to a huge chain of deferred callbacks, which then
overflows the stack when the chain completes. `inlineCallbacks` makes a better
job of this if we use iteration instead.

Clean up the code a bit too, while we're there.

Update opentracing docs to use the unified 'trace' method

Get rid of the labyrinthine `recoverer_fn` code, and clean up the startup code
(it seemed to be previously inexplicably split between
`ApplicationServiceScheduler.start` and `_Recoverer.start`).

Add some docstrings too.

... to save OSes which don't use it from having to maintain a port.

Fixes #5865.

Add authenticated_entity and servlet_names tags.

Functionally:
- Add a tag for authenticated_entity
- Add a tag for servlet_names

Stylistically:
Moved to importing methods directly from opentracing.

Fixes #5833

The emailconfig code was attempting to pull incorrect config file names. This corrects that, while also marking a difference between a config file variable that's a filepath versus a str containing HTML.
