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:
- first archive jobs, and only after submit jobs; this fixes the case...

rapi: rework error handling

Currently the rapi code doesn't have any custom error handling; any
exceptions raised are simply converted into an HTTP 500 error, without
much explanation.

This patch adds a couple of generic SubmitJob/GetClient functions that...

Fix backend.OSEnvironment be/hv parameters

Commit 67fc3042c20f5893abf71a0b4c445c356f9603b9 added some more
variables to be exported to OSEnvironment, but it has two bugs:
- wrong variable name (env vs. result)
- in OSEnvironment we don't have the automatic converstion to strings...

rapi: make tags query not use jobs

Currently the rapi tags query implementation is similar to the command
line one: it submits OpGetTags jobs. This not good, since this being an
API it can be used a lot and can pollute the job queue with many such
trivial jobs....

Change failover instance when instance is stopped

Currently, if the instance is stopped, we still check for enough memory
on the target node. This is a little bit too strict, since in case too
many nodes have failed and one is out of the memory, this prevents...

Export more instance information in hooks

Currently we miss in hooks the instance's hypervisor, hypervisor
parameters and backend parameters. This forces hooks to query back into
ganeti, which is dangerous due to possible luxi sockets exhaustion.

This patch adds these three as INSTANCE_HYPERVISOR, INSTANCE_HV_*,...

watcher: write the instance status to a file

This patch modifies the watcher to keep on-disk a file with the instance
status; this can be used from outside of ganeti to react to instances
being down (when the watcher cannot restart them).
