Eliminating use of Apache Karaf CLI client and of ONOS_USE_SSH env. variable.

All CLI access is now through the raw SSH client.
To enable passwordless access, the 'onos-user-key' tool should be used to add user keys.
Added 'onos-user-password' tool in the similar vein and usage as the 'onos-user-key' tool.
