If possible, replace symbolic links in place

Naive 'ln -s -f a b' will put the link inside 'b', if
'b' is (a symlink to) a directory; so, during upgrades,
the links in $(sysconfdir) cannot be updated this way.
Removing and readding works, however leaves the risk...

Add an upgrade command to gnt-cluster

Add option to redist-conf while queue is drained

Add a new option to 'gnt-cluster redist-conf' allowing to ignore a drained
state of the Ganeti queue. This is needed (until we implement the fine-grained
queue control) during upgrades, as here we have to redistribute the configuration...
