Enhance secondary node replace for drbd8

This (big) patch does two things:
- add "local disk status" to the block device checks
(BlockDevice.GetSyncStatus and the rpc calls that call this
function, and therefore cmdlib._CheckDiskConsistency)
- improve the drbd8 secondary replace operation using the above...

Implement device to instance mapping cache

Currently, troubleshooting DRBD problems involves a manual process of going
backwards from the DRBD device to the instance that owns it.

This patch adds a weak (i.e. not guaranteed to be correct or up-to-date)
cache of device to instance. The cache should be, in normal operation,...

Initial implementation of drbd8 template type

This is a partially working drbd8 template type. It does:
- add/remove
- startup/failover/shutdown

Not working is replace disks, which needs custom code for this template.

The node's ssh keys filenames are now provided as constants; this should
