ltsp-cluster SERVER variable is overwritten by ltsp_config file.

[Marc Gariépy]

[Impact]
when booting a ltsp-cluster thin client I am unable to get my configuration because the variable SERVER is overwritten by the file /var/cache/ltsp/ltsp_config.

So we need to rename SERVER to CC_SERVER in getltscfg-cluster for it to work properly.

[test case]
configure your chroot to use ltsp-cluster.
run getltscfg-cluster -a

the server that it tryed to contact is the nbd-server
When the script is broken, getltscfg-cluster try to do a wget on the nbd-server instead if the control center.
With the patch, i changed the variable name to CC_SERVER to prevent the sourcing of /var/cache/ltsp/ltsp_config to overwrite the variable.

[regression potential]
None : The variable for the ltsp-cluster is changed to CC_SERVER in the script and configuration for ltps-cluster.

[development fix]
I know this section is deprecated but it's actually relevant in this case ;)
The fix hasn't hit quantal yet because of some massive packaging rework going on with LTSP to try and bring us in sync with Debian. I can guarantee that we will have a new upstream release in quantal that will include this fix. ETA is of a couple of weeks.

the patch can be found here:

Hi Marc.

Can you clarify the test case a bit? Its really hard to follow.. I'm not sure what to expect in the case where it is broken, or when it is fixed.

Thanks!
