Fixing depends in metadata.rb and Berksfile

Since renaming identity and image, we need to update
a variety of places, including the Berksfile and metadata.rb
files for all projects that refer to those cookbooks as
dependencies.

Change-Id: Id218e7f6c3d77622b5589722dcdc31c3ace17a13
Removed local patches

These patches make assumptions that are a bit too liberal.
As these cookbooks are more widely used, these should be
moved into a wrapper cookbook.

Changed cookbook name to openstack-compute

Changed the cookbook name to openstack-compute, fixed all tests, and
addressed attributes. Also addressed calls to external services,
primarily keystone -> openstack-identity.

All tests pass.
