Pull request for new cobbler setting

[Christopher Johnston]

https://github.com/chjohnst/cobbler/commit/c5e53f7f36c01eaaaf9f7f47466de2...

I added a new cobbler setting to ensure that all client commands are forced
to use the localhost instead of the server setting.  In my environment we
have cobbler nodes where we provide a remote server for that entry or the
VIP in the cluster (active/standby cobbler nodes).  This is causing
commands like cobbler sync from completing as they can attempt to connect
to the VIP.  The setting defaults to off, but can be turned on if you want
to force connections to the localhost.

Let me know if you have any questions.
