Fix security group race condition while creating rule

Previously, it was possible for someone to create a security group rule
where the rule references another security group. To do this nova would
first create the security group rule and then look up the referenced group
(group_id's) name in order to return that via the api. During this time
it's possible for someone to delete this security group rule and the
referenced group before the call returned resulting in a 404 error being
raised. This patch addresses this issue by looking up the group name
first and then creating the security group rule in order to avoid this
from occuring.

Note: this patch also adds a test to cover the case where an invalid group
id was passed though this does not really add any real additional coverage
to the change largely because the code is currently using global stubs. That
said, the previous coverage should hopefully be sufficient

VMware: cleanup the constructors of the compute drivers

The 'read_only' parameter was never used by the compute drivers.
The 'scheme' parameter should be passed to the base constructor.

VMware: Resize operation fails to change disk size

The finish_migration step will resize the cpu and memory to match
the new flavor chosen, but not the disk size. Additional code was
added to extend the disk size using ExtendVirtualDisk_Task.

Deduplicate module listings in devref

devref already contains a list of all modules, so no need to explicitly
include files that just contain lists of modules under the section 'Module
Reference'. Most of the deleted files are very outdated and refer to
non-existent modules anyway.

Leave services for now as it contains some content
that should be preserved. A later patch will clean those files up.
