HTTP connection keepalives (#2730)
Beforehand we disabled HTTP keepalives to prevent ambient system
resources from being used by excess idle connections. Now that we've
fixed some bugs in the federation API and device list updater, this
situation is now much better and we don't open so many remote
connections anyway.

Keepalives allow us to not have to handshake TLS so often (which is
quite expensive) and reusing an idle connection is much faster than
having to open a new one. This can help with response times when talking
to remote federated servers.

This PR also adds a new option to disable keepalives if needed:

```
  # Disable HTTP keepalives, which also prevents connection reuse. Dendrite will typically
  # keep HTTP connections open to remote hosts for 5 minutes as they can be reused much
  # more quickly than opening new connections each time. Disabling keepalives will close
  # HTTP connections immediately after a successful request but may result in more CPU and
  # memory being used on TLS handshakes for each new connection instead.
  disable_http_keepalives: false
```

Fulltext implementation incl. config (#2480)
This adds the main component of the fulltext search.
This PR doesn't do anything yet, besides creating an empty fulltextindex
folder if enabled. Indexing events is done in a separate PR.

Rate limiting changes (#2519)
* Rate limiting changes

This makes the following changes:

* For logged in users, the rate limiting now applies to the device session rather than the remote IP address;
* For non-logged in users, the rate limiting continues to apply to remote address as it does today;
* It is now possible to add user IDs to the `exempt_user_ids` option under `rate_limiting` to exclude bots from rate limiting;
* Admin and appservice users are now exempt from rate limiting by default.

* Fix build with media API
