Pass --fqdn to ssh hostname checks

The cluster verify checks for fqdn are done via address lookups, and
there we actually use the FQDN. However, for the ssh hostname check
which is done at node add time, we rely on the default of the “hostname”
command. And Debian for example recently changed the default to return...

Add disk cache control parameter for KVM

This patch adds the 'cache' parameter for KVM; currently this is only
customisable at the hypervisor level, so it's the same for all drives
(except any CDROM image, which gets the default).

Change pyinotify import for broader compatibility

On some distributions pyinotify is installed in a different way, and the
actual module just contains an internal pyinotify entry, which is the
actual library. On others the main pyinotify module contains the library...

ClusterMasterQuery: add primary ip field

By allowing also the primary ip field to be fetched directly, we avoid
one more confd lookup, or dns request, to find out which address the
master node lives at.

confd ClusterMasterQuery: allow fields request

Change the ClusterMasterQuery to allow a query, and if present accept a
list of fields to be returned. Currently only name and ip are accepted.

This feature will be used by NLD to route the cluster ip over the nbma....

DRBD: ignore unreadable meta devices

The DRBD driver can ignore dead disks but not dead meta devices (for
which it refuses to configure the minor). To handle this case, we check
that the meta device is readable and if not we ignore it (the same as
when backend._RecursiveAssembleBD didn't find it)....

Simplify utils.ReadFile

The documentation for file objects' read method states that if the size
is "negative or ommitted", all data is read; thus we can simplify it to
have size=-1 by default and not have the if test.

gnt-cluster verify: Warn if node time diverges too far

The warning will be generated if the clocks diverge by more
than 150 seconds. Due to the way the RPC system works, we
cannot get exact time differences, e.g. if one of the
queried nodes is broken. The comparision is done using a...

KVM: fail when a routed nic has no ip

This shouldn't happen, but if it does it's better to fail at this level,
rather than create a broken NIC script, which is hard to debug.

cmdlib: Work around race condition in DRBD before version 8.0.13

DRBD goes into sync mode for a short amount of time after
executing the "resize" command. DRBD 8.x below version
8.0.13 contains a bug whereby calling "resize" in sync
mode fails.
