Matt Riedemann 622bfb2e95 Handle uuids in os-hypervisors API
There are quite a few changes here as this is not only handling
uuids for the hypervisor id but it's also a refactor in several
APIs for consistency.

The main changes are detailed in the REST API Version History
doc in this change, but to summarize the changes:

* Hypervisor and service IDs are handled as the UUIDs for those
  resources; this is necessary for accurately working with these
  resources across multiple cells.
* The 'servers' and 'search' routes are deprecated and folded into
  the index and detail methods as query parameters, validated using
  json schema.
* The show method will also be able to return the list of servers
  hosted on the given hypervisor using the with_servers query
  parameter.
* The marker used when paging over lists of hypervisors is the
  compute node UUID.
* Using the hypervisor_hostname_pattern query parameter will not
  work with paging parameters.
* API reference docs are updated for the detailed changes.
* Functional and unit tests are provided for all changes.

all compute nodes, shows details for a hypervisor, shows the uptime
for a hypervisor, lists all servers on hypervisors that match the given
``hypervisor_hostname_pattern`` or searches for hypervisors by the given
``hypervisor_hostname_pattern``.
