Document use of server_settings argument with asyncpg.connect

[adamrothman]

I was browsing the docs earlier and noticed the server_settings argument to asyncpg.connection.connect. It's described as "an optional dict of server parameters" – but there's no mention of what these parameters are, and no example (that I could find, anyway) of how/when to use this argument.

Thanks!

I'll add the link to the docs.
