Update NEWS for version 2.9



Also for version 2.9, sort the news entries into incompatible and
compatible changes. In this way, we keep the list of items that have
to be taking into considerations before upgrading as short as possible.

Also mention that our tests now have an additional dependency.

*(unreleased)*
- DRBD 8.4 support. Depending on the installed DRBD version, Ganeti now uses
the correct command syntax. It is possible to use different DRBD versions
on different nodes as long as they are compatible to each other. This
enables rolling upgrades of DRBD with no downtime. As permanent operation
of different DRBD versions within a node group is discouraged,
``gnt-cluster verify`` will emit a warning if it detects such a situation.

- hroller now also plans for capacity to move non-redundant instances off
any node to be rebooted; the old behavior of completely ignoring any
non-redundant instances can be restored by adding the --ignore-non-redundant

- On instance creation, disk templates no longer need to be specified
with '-t'. The default disk template will be taken from the list of
enabled disk templates.
- New "inst-status-xen" data collector for the monitoring daemon, providing
information about the state of the xen instances on the nodes.
- New "lv" data collector for the monitoring daemon, collecting data about the
logical volumes on the nodes, and pairing them with the name of the instances
they belong to.
- New "diskstats" data collector, collecting the data from /proc/diskstats and
presenting them over the monitoring daemon interface.
- The monitoring daemon is now running as root, in order to be able to collect
information only available to root (such as the state of Xen instances).
- The ConfD client is now IPv6 compatible.
- File storage is no longer dis/enabled at configure time, but using the
option '--enabled-disk-templates' at cluster initialization and
modification.
