Add more doc comments for MySQL/PostgreSQL connection URIs

Note that Diesel implements its own parser for MySQL connection URIs, so it
probably doesn't accept the full range of syntax that would be accepted by
MySQL's client libraries, whereas for PostgreSQL, Diesel simply passes the
connection string/URI to PostgreSQL's libpq for processing.
