Title: [openstack|compute] rename meta_hash to to_hash; make it public

OpenStack's metadata class has a private `meta_hash` method. OpenStack metadata can be represented by a hash, and it'd be super rad to be able to do so.

This commit changes that method to be called `to_hash` and makes it a public method.
