Abstract check that an instance is down

Multiple LUs require that an instance is not running while they operate
on the instance (reinstall, rename, modify, recreate disks, deactivate
disks). The code to do this check is duplicate many times, and not very...

Abstract node free disk space check

Both create instance and grow disk check the free disk space on nodes
using the same, duplicate code. Since we'll need this in other places in
the future, we abstract the check into a new function.

The patch adjusts the error message to be more in-line with the one for...

Abstract disk template verification

This is a simple check, but we'll need it in multiple places.

Implement disk adoption mode in gnt-instance

This patch modifies the parsing of the “--disk” argument to instance
create to accept “adopt” as a valid key, which builds the correct disk
structure for OpCreateInstance.

LUCreateInstance: implement disk adoption mode

This new mode, valid only for the plain template disk, allows creation
of an instance based on existing logical volumes (preserving data),
rather than creation of new volumes and OS creation.

The new mode works as follows:...

ConfigWriter: add an LV reservation manager

This patch adds an LV reservation manager to be used for LV names. Since
we now have four such managers, we create a list for easier release.

Implement replacing cluster certs and keys via “gnt-cluster renew-crypto”

Recent changes to “gnt-cluster verify” made it complain on expiring SSL
certificates. While it was possible to replace the SSL certificates and
other cluster secrets manually before, doing so was cumbersome. Cluster...

cli: Add helper function to stop and start whole cluster

Replacing cluster certificates and keys requires all cluster daemons to be
shut down. This might also be handy for the cluster merger tool, though
the function might need a few more extensions.

bootstrap: Add new function to create cluster certs and keys

The code to generate cluster certificates, keys and secrets is currently
spread over several places. It makes sense to move it to a separate
function as we want to provide the user with the ability to automatically...
