Adds server port argument to legacy modules (#2444)

This patch adds support for the server_port module. It
additionally updates the documentation in the module for
it.

The changes were tested in the f5-ansible repository to
ensure no breaking changes were made. This argument allows
modules to be used on BIG-IPs that are listening on
non-standard ports.
