This patch consists of minor cosmetic enhancements for increased
readability, mainly, with some minor fixups explained in specific
commits.
Cosmetic changes, no need to backport.

test_ssl: fix indentation
generic_server: improve logging broken TLS connection
test_ssl: improve timeout and readability
alternator/server: update SSL comment
We have four native transport ports: two for plain/TLS, and two
more for shard-aware (plain/TLS as well). Add four more that expect
the proxy protocol v2 header. This allows nodes behind a reverse
proxy to record the correct source address and port in system.clients,
and the shard-aware port to see the correct source port selection
made my the client.
Before this change, new connections were handled in a default
scheduling group (`main`), because before the user is authenticated
we do not know which service level should be used. With the new
`sl:driver` service level, creation of new connections can be moved to
`sl:driver`.
We switch the service level as early as possible, in `do_accepts`.
There is a possibility, that `sl:driver` will not exist yet, for
instance, in specific upgrade cases, or if it was removed. Therefore,
we also switch to `sl:driver` after a connection is accepted.
