Increase the thread size to 5

Now that we use the locking library to make sure running opcodes cannot
step on each other toes we can have a bigger thread size, and
potentially process many opcodes in a parallel manner.

Processor: pass context in and use it.

The processor used to create a new ConfigWriter when it was initialized.
We now have one in the context, so we'll just recycle it. First of all
we'll pass the context in when creating a new Processor object, then
we'll just use context.cfg, which is granted to be initialized, wherever...

ganeti-masterd: init and distribute common context

This patch creates a new GanetiContext class, which is used to hold
context common to all ganeti worker threads. As for the
GanetiLockingManager class it is paramount that there is only one such
class throughout the execution of Ganeti, so the class checks for that,...

Handle any exception in ganeti-masterd

If an uncaught exception is thrown currently it destroys the calling
thread. This patch changes the behaviour to failing the current job,
logging a message, but trying to keep the daemon up.

Fail job on ganeti exceptions

When a Job raises a ganeti exception a message is printed but nothing is
reported in the job itself. It's better to update the job status, thus
notifying the client, possibly polling for the job result, of what went
wrong.

Disable forking in the master daemon

This patch adds a mechanism to disable utils.RunCmd in selected
programs. This is needed in the master daemon unless we confirm
threading doesn't pose any problems.

This makes cluster init fail, but creating new trunk clusters is anyway...

Move the 'cmd' lock from cli.py to ganeti-masterd

This patch removes the lock and the lock options from cli.py and moves
them to the master.

Later during development we can remove it completely, but for now it's
good to protect any other tool that uses the lock directly....

Convert cli.SubmitOpCode to use the master

This patch converts the cli.py SubmitOpCode method to use the unix
protocol and thus execute the opcodes via the master.

The patch allows a partial burnin to work with the master. Currently the
query opcodes, since they are executed via the SubmitOpCode, are...

Add per-opcode results to job processing

This patch changes the definition of a job and introduces per-opcode
results.

First, the result and status fields of a job are condensed into a single
'status' attribute. Then, we introduce an opcode status and one result...

Implement forking/master role checking in masterd

This patch adds checks for the master role and daemonize support to
ganeti-masterd.

The patch modifies the startup/shutdown of the server because:

Add a simple gnt-job script

This patch adds a very basic gnt-job script that allows job querying.
This goes on top of the previous master daemon patches.

Currently, because of the not-changed cmd lock, you can't query the jobs
as long as a job is running - you have to rm the cmd lock and then you...

Initial tests with ganeti-masterd

This patch adds a very in-progress master daemon. This needs to be
launched manually, does not background itself, but can be used for
opcode execution.

Also parts of this code should be moved to luxi.py.
