This patch adds a ‘role’ node list field, which shows a one-character
node status. This is a simpler way to see the node status than selecting
all the flags individually.

This (somewhat big) patch adds support for remotely rebooting the nodes
via whatever support the hypervisor has for such a concept.

For KVM/fake (and containers in the future) this just uses sysrq plus a
‘reboot’ call if the sysrq method failed. For Xen, it first tries the
above, and then Xen-hypervisor reboot (we first try sysrq since that
just requires opening a file handle, whereas xen reboot means launching
an external utility).

The user interface is:

    # gnt-node powercycle node5
    Are you sure you want to hard powercycle node node5?
    y/[n]/?: y
    Reboot scheduled in 5 seconds

The node reboots hopefully after sending the reply. In case the clock is
broken, “time.sleep(5)” might take ages (but then I suspect SSL
negotiation wouldn't work).

This patch modifies the start instance script, opcode and logical unit
to support temporary startup parameters.

Different from 1.2, where only the kernel arguments were supporting
changes (and thus xen-pvm specific), this version supports changing all
hypervisor and backend parameters (with appropriate checks).

This is much more flexible, and allows for example:
  - start with different, temporary kernel
  - start with different memory size

Note: in later versions, this should be extended to cover disk
parameters as well (e.g. start with drbd without flushes, start with
drbd in async mode, etc.).

In Ganeti 1.2, “none” was used to signify no initrd. In 2.0 we have
changed to “no_” as a prefix (i.e. “-H no_initrd_path”) and thus we
document in the manpage this.

The QA suite is changed accordingly.

Sometimes reinstalls are slightly different than new installs. For
example certain partitions may need to be preserved accross reinstalls.
In order to do that on a per-os basis we pass in the INSTANCE_REINSTALL
variable to inform the create script about when a reinstall is
happening.

Currently “gnt-debug submit-job” takes a single argument and has
non-trivial startup-costs; in order to exercise the job system, it is
better to be able to submit multiple jobs with a single invocation of
the script.

This patch extends it to take multiple argument, de-serialize the
opcodes and then submit all of them as fast as possible, in order to
increase pressure on the master daemon.

In 1.2, due to the md+drbd7 legacy, we had a complex choice of replace
modes, and the new drbd8 modes where forced into this syntax, with some
complicated rules of transition from one mode to another (if REPLACE_ALL
but not new node passed, switch to REPLACE_SEC, etc.).

This patch cleans this situation by making a clear separation between
the two main modes:
  - replace on current nodes (with the two sub-cases on primary and on
    secondary)
  - change to a new node (either via manually specified node or via
    iallocator)

This (big) patch reworks the master startup/shutdown and the fixes the
master failover.

What does the patch do?

For master start/stop:
  - remove the old ganeti-master script and its associated man page
  - moves the ip start/stop directly into the backend.(Start|Stop)Master
  - adds start/stop of the master/rapi daemon into these functions,
    selectively based on the start/stop arguments
  - makes the master call via rpc StartMaster(start_daemons=False) to
    the local node so that the master IP is started
  - and finally changes the example init.d script to directly start and
    stop all three daemons, since they do the right thing (depending on
    master/not master role)

For master failover:
  - moves the code from LUMasterFailover into bootstrap.MasterFailover,
    since we need to start/stop the master during this operation and
    thus it can't be executed from the master
  - removes the LUMasterFailover and its associated opcode

Notes: ubuntu's /etc/lsb-base-logging.sh is dumb, so the messages 'not
master' are not seen during startup on non-master nodes.
