Adding type and port parameters to ssh_known_hosts_entry LWRP

Several sites run ssh on non-standard ports, i.e. 2222 or 443.  Also, on older versions of RHEL, `ssh-keyscan` defaults to rsa1, which if you are running only ssh v2, will silently fail.

This patch works around the above issues by adding `port` and `type` parameters to the LWRP.
