First: This enables the use of “gnt-job watch $id” for archived jobs.

Now, the reason for actually making this work is that during
sufficiently large group or node evacuations jobs are archived before
the client gets to poll for their output. This led to situations where
the jobs would finish successfully, but the client reported an error
because it couldn't see the job anymore.

Check if extstorage's log dir exists on the host machine, before

During attach the logfile is `None'. If the attach script
fails and we try to Tailfile() its logfile, TailFile
breaks with:

Thus, we don't show the logfile, if ExtStorage's attach script fails.
Just throw the appropriate error.

To help developing Ganeti on newer distributions, let's try to fix
pylint warnings/errors. I'm using pylint from current Debian wheezy:
pylint 0.25.1, astng 0.23.1, common 0.58.0, and we have 3 things that
needs fixing.

First, a really wide "except", with the silencing in the wrong
place. I'm not sure why this doesn't have "except Exception", so let's
add it. However, pylint still complains about "Catching too general
exception", even though we do want to catch both system and our
exception, so let's add a silence for W0703. It's true that we
shouldn't catch KeyboardInterrupt and friends, but that should be
cleaned up on the master branch.

Second, pylint complains about "redefining name builtin tuple",
because we do some pattern matching in the except blocks in
netutils. This seems to be a false positive, but let's clean the code
around this.

And finally, type inference again goes bad, so let's silence E1103
with its "boolean doesn't have 'get' method".

After this, I can run "make lint", and by extension "make
commit-check" on Debian Wheezy, yay! We might be able to bump our
required pylint versions to something not ancient…

Pylint version:

I found out that simply using a shortened name will 'fix' this issue,
so let's do this to allow running newer pylint versions.
