This adds a new service called "nova-conductor" which will provide
services for nova-compute, such as completing database updates and
handling long-running tasks.
Right now, this just adds a fraction of the database-related work
so that we can proceed with incremental changes to nova-compute.
For compatibility/flexibility, both LocalAPI and (RPC)API classes
are provided. Users concerned with performance or compatibility
who wish to maintain compute-node-local database accesses can
set the [conductor] use_local=True, which will mimic the legacy
behavior.

This removes the majority of the nova-volume code from the codebase.
It updates relevent config options to default to cinder. It updates a
number of existing tests that were depending on code that was removed.
A few things still need to be removed:
* volume/driver.py & volume/iscsi.py
These files are used by the libvirt volume driver tests. These
tests should be updated to mock the relevant calls.
* scheduler/simple.py & scheduler/multi.py
These files should no longer be necessary so they can be removed
in a subsequent patch
* exception.py cleanup
Once the above files are removed there are a number of unused
exceptions which can be removed
* database calls and database tables
The database calls have not been removed and the tables have not
been dropped. This can be done in a separate migration
* additional config options and nova.conf.sample
There may be a few extra config options that can be removed and the
conf sample can be regenerated
