KVM: use cache=none for shared disk templates

Disable host cache for externally mirrored disks to avoid cache incoherency.
Without this, migrations between the same two nodes may end up in disk

This is a runtime override of cluster defaults, mostly a workaround....

Instance failover: fix bug for INT_MIRROR cases

Patches db366d9a and aac4511a added support for EXT_MIRROR instances,
but inadvertently introduced a bug: for INT_MIRROR cases, we don't
need (actually we can't support) neither an iallocator nor a target

Allow disk adoption during disk addition

It is now possible to allow adopting a disk during gnt-instance modify time, as

gnt-instance modify --disk add:adopt=/path/to/disk (blockdev)
gnt-instance modify --disk add:adopt=<lvname> (plain)

We do the same checks as during instance creation....

Fix parts of shared storage migration

Commit faaabe3c fixed failover behaviour for DTS_INT_MIRROR instances, however
it broke migration for DTS_EXT_MIRROR instances, by moving iallocator and node
checks from LUInstanceMigrate to TLMigrateInstance. This has the side-effect...

Add completion suggestion for more parameters

Add suggestions for disk-, nic-, and backend-parameter completion.

Also alter autotools/build-bash-completion to ignore the new suggestion types
for the moment.

Allow KVM to boot from HTTP

New versions of KVM support booting from HTTP-hosted ISO
images, via libcurl. This patch adds a proper check to
allow defining either a sane, absolute path or an HTTP
URL as an iso image path.

Remove "format=raw" from the cdrom device options when iso_image...

Prevent ssconf values from having non-string values

For whatever reason, my test cluster managed to acquire
shared_file_storage_dir with a None value, instead of empty
string. This is not flagged in masterd itself, but the node daemon
will fail in writing the value to disk, as it calls len() on the...
