Allocate a new default group for supernova client with large ID no. (#267)

* Allocate a new default group for supernova client with large ID no.

Supernova ignores maxlogins value and keeps assigning consecutive numbers to remote clients.  If clientID is larger than maxlogins, supryia raises KeyError trying to access self._node[self.clientID + 1]

* Revert "Allocate a new default group for supernova client with large ID no."

This reverts commit 3aa7e4389d29950c0994236083ebd2bcf80a1924.

* Fall back to Server._options.maximum_logins value if supernova doesn't provide a value
