Convert os_diagnose rpc to new style result

This also removes custom post-processing from rpc.py; since this call
has only one user, it was simple to move it back to the caller.

Convert instance_list rpc to new style result

Since backend.GetInstanceList() is used both as RPC endpoint and as
internal function, it can't return (status, value). Instead it returns
only valid instance info, and failures are denoted by exceptions; and...

Convert node_has_ip_address rpc to new style

This should actually have a function in backend, but it's fine for now.

Convert node_start_master to new style result

This is used in multiple places outside cmdlib.py, so it's a more
interesting patch.

Convert volume_list rpc to new style result

This is a big change, because we need to cleanup its users too.

The call and thus LUVerifyDisks LU used to differentiate between failure
at node level and failure at LV level, by returning different types in
the RPC result. This is way too complicated for our needs....

Convert export_info rpc to new style result

This also removes some code from ganeti-noded and rpc.py, which should
not do such processing of data (and be simply glue code). (Or
alternatively they could, if we had better infrastructure).

rpc: Add a simple failure reporting framework

This patch adds a simple failure reporting tool, similar to bdev's
_ThrowError. In backend, we move towards the new-style RPC results (of
type (status, payload)) and thus functions which use this style can very...

Add a node powercycle command

This (somewhat big) patch adds support for remotely rebooting the nodes
via whatever support the hypervisor has for such a concept.

For KVM/fake (and containers in the future) this just uses sysrq plus a
‘reboot’ call if the sysrq method failed. For Xen, it first tries the...

watcher: automatically restart noded/rapi

This patch makes the watcher automatically restart the node and rapi
daemons, if they are not running (as per the PID file).

This is not an exhaustive test; a better one would be TCP connect to the
port, and an even better one a simple protocol ping (e.g. get / for rapi...

watcher: handle full and drained queue cases

Currently the watcher is broken when the queue is full, thus not
fulfilling its job as a queue cleaner. It also doesn't handle nicely the
queue drained status.

This patch does a few changes:

Add a luxi call for multi-job submit

As a workaround for the job submit timeouts that we have, this patch
adds a new luxi call for multi-job submit; the advantage is that all the
jobs are added in the queue and only after the workers can start
processing them....
