Share SSL contexts for non-federation requests (#7094)
Extends #5794 etc to the SimpleHttpClient so that it also applies to non-federation requests.

Fixes #7092.

Remove unnecessary parentheses around return statements (#5931)
Python will return a tuple whether there are parentheses around the returned values or not.

I'm just sick of my editor complaining about this all over the place :)

Erik Johnston f299c5414c Refactor MatrixFederationAgent to retry SRV.
This refactors MatrixFederationAgent to move the SRV lookup into the
endpoint code, this has two benefits:
	1. Its easier to retry different host/ports in the same way as
	   HostnameEndpoint.
	2. We avoid SRV lookups if we have a free connection in the pool

Erik Johnston e6e136decc Retry well known on fail.
If we have recently seen a valid well-known for a domain we want to
retry on (non-final) errors a few times, to handle temporary blips in
networking/etc.

Erik Johnston 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.

Erik Johnston af9f1c0764 Add a lower bound for TTL on well known results.
It costs both us and the remote server for us to fetch the well known
for every single request we send, so we add a minimum cache period. This
is set to 5m so that we still honour the basic premise of "refetch
frequently".

Fix idna and ipv6 literal handling in MatrixFederationAgent (#4487)
Turns out that the library does a better job of parsing URIs than our
reinvented wheel. Who knew.

There are two things going on here. The first is that, unlike
parse_server_name, URI.fromBytes will strip off square brackets from IPv6
literals, which means that it is valid input to ClientTLSOptionsFactory and
HostnameEndpoint.

The second is that we stay in `bytes` throughout (except for the argument to
ClientTLSOptionsFactory), which avoids the weirdness of (sometimes) ending up
with idna-encoded values being held in `unicode` variables. TBH it probably
would have been ok but it made the tests fragile.

Fix Host header sent by MatrixFederationAgent (#4468)
Move the Host header logic down here so that (a) it is used if we reuse the
agent elsewhere, and (b) we can mess about with it with .well-known.
