Introduce the rbd disk template, which handles provisioning and
management of instance disks as block devices mapped to rbd volumes
on a RADOS cluster.

The rbd template is of type DTS_EXT_MIRROR, meaning rbd-based
instances can failover or migrate to any node, without
primary-secondary limitations.

Use of this template requires the rbd kernel driver and rbd tool
on all VM-capable nodes, as well as an operational RADOS cluster,
accessible by them.

Add new --maxmem-size and --minmem-size options.
The old --mem-size option allows setting both at the same time.
If --minmem-size is lower than --maxmem-size execute a runtime memory
change on all instances, bringing them to their minimum memory size.

In version 0.21, pylint unified all the disable-* (and enable-*)
directives to disable (resp. enable). This leads to a lot of
DeprecationWarning being emitted even if one uses the recommended
version of pylint (0.21.1, as stated in devnotes.rst).

This commit changes all the disable-msg directives to disable.

burnin is a cluster/testing feature, so it makes sense that a hidden OS

This patch changes the behaviour of OpDiagnoseOS with regards to the
'valid' field to be similar to the one for the hidden/blacklisted
fields: unless this field is requested, invalid OSes are filtered out.

The rationale is that, except for the gnt-os info/diagnose, all other
users of this opcode are requesting the valid field just to filter out
invalid OSes, and not for any other use. Thus, changing this behaviour
makes these callers simpler.

If we call burning with only existing instance, then it will fail to
create any of them, and thus in the removal phase it won't have anything
to remove. Since calling luxi.SUBMIT_MULTIPLE_JOBS with an empty job set
is an error (and will raise an exception), this creates a very strange
error in burnin (which is unfortunately hidden by ExecJobSet()).

As such, we modify CommitQueue to return immediately if it has an empty
op queue.

After some more investigation, only the soft reboot type fails for Xen
3.4 (due to the reboot/uptime time counter). As such, it's better to
allow selective testing, since we do want to test in general these

This makes it compatible with the python builtin, and we can even use
the builtin when running under the right version of python. The all and
any functions are renamed to _all and _any, so that they can be tested,
and (non)existing unittests are updated (translation: there are no unit
tests, so none are updated).

This patch also moves the code deciding which partial to use next to
the definition of the _partial function, rather than after TryToRoman.
