Move the luxi error handling into errors.py

Currently the luxi error handling is hardcoded as special encoding on

moves it to errors.py such that other parts of the code can reuse the
same encoding....

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

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

This patch adds a very basic gnt-job script that allows job querying.

This patch adds a very in-progress master daemon. This needs to be

opcode execution.

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