Set SNI to the server_name, not whatever was in the SRV record

Bump timeout on get_missing_events request

When we do a join, always try the server we used for the alias lookup first.

Fixes #2418

We want to wait until we have read the response body before we log the request
as complete, otherwise a confusing thing happens where the request appears to
have completed, but we later fail it.

To do this, we factor the salient details of a request out to a separate
object, which can then keep track of the txn_id, so that it can be logged.

Fix some b'abcd' noise in logs and metrics

Python 3 compatibility: make sure that we decode some byte sequences before we

Remove nuke-room-from-db.sh script

The problem with this script is that it is largely untested, entirely
unmaintained, and running it is likely to make your synapse blow up in
exciting ways.

For example, it leaves a bunch of tables with dead values in it, like
event_to_state_groups.

Having it here sends a message that it is a supported part of
synapse, which is absolutely not the case.
