When an opcode fails, the job queue would leave following opcodes as “queued”,
which can be quite confusing. With this patch, they're all marked as failed and
assertions are added to check this.

The workerpool should not keep any reference to task arguments after

We modify the regex used to match that with an optional parts which is

Furthermore it adds unittests that test for these different cases. Now
the data read from /proc is passed into the _GetVersion method, which
makes testing easier.

This patch fixes two issues with job archival. First, the
LoadJobFromDisk can return 'None' for no-such-job, and we shouldn't add
None to the job list; we can't anyway, as this raises an exception:

  node1# gnt-job archive foo
  Unhandled protocol error while talking to the master daemon:
  Caught exception: cannot create weak reference to 'NoneType' object

After fixing this, job archival of missing jobs will just continue
silently, so we modify gnt-job archive to log jobs which were not
archived and to return exit code 1 for any missing jobs.

If we call burning with only existing instance, then it will fail to
create any of them, and thus in the removal phase it won't have anything
to remove. Since calling luxi.SUBMIT_MULTIPLE_JOBS with an empty job set
is an error (and will raise an exception), this creates a very strange
error in burnin (which is unfortunately hidden by ExecJobSet()).

As such, we modify CommitQueue to return immediately if it has an empty
op queue.

Currently, we require both --force and --force-multiple for skipping the
confirmation on instance reinstalls. After offline conversations, this
has been deemed to be excessive, and this patch changes the meaning of
--force-multiple to be a “stronger” force, and not require both.

So, to skip the prompts:
- single instance reinstallation requires either --force or
  --force-multiple
- multiple instance reinstallation requires --force-multiple

Currently, if a job execution raises a Ganeti-specific error (i.e.
subclass of GenericError), then we encode it as (error class, [error
args]). This matches the RAPI documentation.

However, if we get a non-Ganeti error, then we encode it as simply
str(err), a single string. This means that the opresult field is not
according to the RAPI docs, and thus it's hard to reliably parse the
job results.

This patch changes the encoding of a failed job (via failure) to always
be an OpExecError, so that we always encode it properly. For the command
line interface, the behaviour is the same, as any non-Ganeti errors get
re-encoded as OpExecError anyway. For the RAPI clients, it only means
that we always present the same type for results. The actual error value
is the same, since the err.args is either way str(original_error);
compare the original (doesn't contain the ValueError):

  "opresult": [
    "invalid literal for int(): aa"
  ],

with:

  "opresult": [
    [
      "OpExecError",
      [
        "invalid literal for int(): aa"
      ]
    ]
  ],

Since we don't support upgrades from 1.2.4 without restarting the
instance, the 'not restarted since 1.2.5' check/error is
wrong/misleading.

Since the live migration works anyway without the links (it recreates
them during the disk reconfiguration anyway), we remove the check and we
transform it into a warning (to the node daemon log only,
unfortunately).

For 2.3, we'll need to change the symlink creation from instance start
time to disk activation time (but that requires more RPC changes).
