Fix libvirt rescue to work with whole disk images

 * fixes bug 1007266
 * passes rescue image data to get_config so it only adds
   the kernel and ramdisk if necessary
 * adds tests to make sure that the kernel and ramdisk
   only appear if they are needed

Implements resume_state_on_host_boot for libvirt.

Adds a new virt driver function to help resume guest states
on host boot. This fixes a couple issue with using a reboot
(like we did previously):

 * Using reboot would clear some task states (VERIFY_RESIZE for example)
 * Provides a mechanism for hypervisor specific guest restarts.
   Reboot would not have worked for XenServer for example...
 * Updates libvirt to use a hard reboot (instead of soft)

Fixes LP Bug #985162.

Add remove_volume_connection to the compute rpcapi.

Part of bug 1006467.

Add the remove_volume_connection method to the compute rpcapi.  This is
used by the compute manager.

Add get_instance_disk_info to the compute rpcapi.

Part of bug 1006467.

This patch adds get_instance_disk_info to the compute rpcapi, which is
used by the scheduler.

Add shared_storage_test methods to compute rpcapi.

Part of bug 1006467.

This patch adds 3 methods used to check if shared storage works between
two compute hosts to the compute rpcapi.  These methods are used by the
scheduler.

This also cuts down on some duplicated code in test_scheduler.

Fix up protocol case handling for security groups.

Fix bug 985184.

When creating security group rules, any case for the protocol was
accepted as input, such as TCP, Tcp, tcp, etc., and was stored in the
database as specified.  However, unless specified as all lowercase, the
code to apply the rules would break and result in some rules not being
applied.

undesirable behavior

Update libvirt imagecache to support resizes.

Updates the libvirt image cache manage so that it accounts
for instances which are resizing.

Also fixes an issue where an exception was thrown when
the image cache manager ran while instances were resizing.
This is because instances which are resizing may have files in the
Nova instances directory which are missing backing files.

Fixes LP Bug #1006616.
