Add Core, Ram and Disk filter to fake virt setting

The FakeVirt driver shouldn't need custom scheduling options, so it run
instead of a real virt driver for testing purposes. This simplifies the
use case where someone wants to run the FakeVirt driver along side a
real driver so someone can test there cloud application without wasting
real instances.

Since the FakeVirt driver should look like it has near infinite resources,
turn on Core, Ram and Disk filters to make sure the drive works with them
enabled.

Install MySQL-python for keystone with rpm system

MySQL-python is needed for keystone and we were installing it
implicitely only for apts and not for rpms. Fix keystone only devstack
install on a pristine vm.

Make Swift uses API_WORKERS

Keep the default to 1 instead of going wild, cause Swift really would
kill the VM if we let it go (and keeps the old behavior).

Updates DevStack to match Zaqar's API name change

Zaqar is a messaging service which provides support for different
messaging patterns and messaging related semantics.
This fix changes the old API name -queuing- to a more accurate name, -messaging-.

Configurable Keystone admin workers

The API_WORKERS option wasn't setting the number of admin workers
for the Keystone server when running in eventlet mode. This will
allow for control of throughput and memory usage.

Function for auth_token middleware config

Each project was configuring the auth_token middleware using several
lines of inisets. Since all the projects should configure the
auth_token middleware in the same way create a function and call it.

Configurable token hashing algorithm

The Keystone server and auth_token middleware were enhanced to
support a configurable hash algorithm.

With this change, the user can set

 KEYSTONE_TOKEN_HASH_ALGORITHM=sha256

in their localrc to use the SHA256 algorithm rather than the
default md5. Any hash algorithm supported by Python's hashlib can
be used. The MD5 algorithm doesn't provide enough protection from
hash collisions and some security standards mandate a SHA2 hash
algorithm.
