With the quorum queue code, RabbitMQ probably still works with Erlang
20.x, but it is not thoroughly tested. Thus, bump the requirement to
Erlang 21.0.
Rate metrics for monitoring of high connection churn scenarios
[#160943831]
It has been reported that in order to use the Erlang client, the
Erlang/OTP source must be available. This is due to one include
file that rabbit_net required. This dependency has been removed.

Instead of calling is_record(sslsocket) the macro ?IS_SSL will
now perform the same test manually (check that it is a tuple,
that the size is correct and that the first element equals sslsocket).

The tuple has not changed in a very long time so doing this
manually is at least as safe as including this private header
file (it could be removed or moved at any time).

Once Erlang/OTP 22 gets out and we know how sockets will be
represented with the NIF implementation, we could revise this
and check whether the socket is one that gen_tcp accepts
(currently it's a port, but this will probably change when
a NIF is used).

It looks like some changes are unrelated to the quorum queue, like connection_churn_metrics. Should this branch be merged with master?

QQ branches had master/stable (in the docs) merged into them to reduce the delta. I'm not sure what the suggestion is, they are going to be merged into master soon.

It would be nice to see the actual changes without noise.
