This reverts commit 289, as the node failover functionality was already
implemented in gnt-node (as opposed to gnt-instance). My mistake.

This patch fixes the documentation in a few cases and adds handling of
the situation where no instance is selected due to too restrictive
options given.

This patch adds the same style of multi-instance selection as in
shutdown/startup to the failover subcommand, with the exception that we
cannot failover with --node or --all (it doesn't make sense).

Currently we ignore errors on instance shutdown (on the source node)
during instance failover. We should do this only if the user gave a
command line options allowing this, as it's a dangerous thing to do.

This patch fixes this by using the same "--ignore-consistency" option
for deciding whether to continue or abort. It also expands a bit the man
page.

This patch series implements the reboot command for gnt-instance. It
supports three types of reboot: soft (hypervisor reboot), hard (instance
config rebuild and reboot) and full (full instance shutdown and startup
again).

This patch contains the gnt-instance script and the man page for it.

This patch adds a new option to the instance removal command
"--ignore-failures" that forces the removal of the instance from the
configuration even if the removal process encounters errors.

In order to be able to do this when the remote node(s) is(are) down, we
need to restrict the execution of the instance removal hook to the
master only. I think this is a reasonable trade-off (but I'm not sure).

This patch adds a '--from' option to the {add,remove}-tags commands that
allows the command to read from a file or from stdin (when passing a
dash for the filename).

This is an initial version of the multi-instance start/stop, which
allows the gnt-instance startup and shutdown subcommands to work on
multiple instances at once.

The available selections are:
  - "gnt-instance startup --instance name..." which is the default, and
    if passed only one argument it behaves like the original command)
  - "gnt-instance startup --node name..." will work on all instances
    having either primary or secondary one of the passed names
  - "gnt-instance startup --primary name..." will work on all instances
    having primary node one of the passed names
  - "gnt-instance startup --secondary name..." will work on all
    instances having as secondary node one of the passed names
  - "gnt-instance startup --all" will work on all instances

This allows a simple cluster-wide shutdown or node shutdown (or
startup).

Note that this version stops at the first error - it will not try to
start the 2nd instance selected if there is a critical error with the
1st one.

Also note that this version is not faster than simply running manually
"gnt-instance shutdown NAME", because it doesn't parallelize the
shutdown/startup actions.

The manpage wrongly states that the default unit for disk sizes is
gibibytes, whereas currently it's mebibytes. Fix that and also update
the '--help' output to display the default unit.
