A failed gnt-cluster (de)activate-master-ip would not produce any output
to the user. This patch adds code that checks for the results of the
RPCs and raise an exception if appropriate.

Add the RunLocalHooks decorator, that allows the execution of hooks
locally. Also, add a RunLocalHooks method to HooksRunner, to adapt the
signature of HooksRunner.RunHooks to the one expected by HooksMaster,
and also to check that the hooks are being executed locally.

- remove any dependence on Logical Units from the HooksMaster;
- add a new function parameter to the constructor, a function that is
  expected to convert the results of the hooks execution in a format
  understood by the HooksMaster;
- add a factory method that builds a HooksMaster from a LU, keeping the
  interface of the old constructor of HooksMaster;
- remove usage of Processor.hmclass from external classes, introducing
  the Processor.BuildHooksMaster method;
- update unit tests.

On a master failover some of the archive dirs might have wrong
permissions in the non-root model. This is due to the nature of noded
still running as root and the job queue is synced that way. This patch
will fix this behaviour by setting the permissions accordingly.

Rather than just allowing files for all nodes to be optional, we allow
optional files to be per-category. The way this works is that they must
be included in both lists (the new code checks for this).

The code also removes a duplicate assert (present both in verify and
compute ancillary files) and checks the new functionality in unittests.

These lists will be used to declare some of the files not necessarily
needed on all nodes. The files selected are files without which the
various hypervisors can still work, but that when they are present
should be synchronized across the cluster (or node group).
