Support of an alternate pypi server

Currently pip will get the package from the https://pypi.python.org server.
For CI, it's a problem as Internet connection can be down,
the pypi server down, etc...

The usecase is for a company/user that maintain a local pypi mirror
and give the option to use this server instead of the official one

Configure the OVS datapath type with devstack.

This feature provides the user with a means of easily configuring
the required Openvswitch datapath type. (Netdev, dpdk, etc)

Define the OVS_DATAPATH_TYPE variable in the devstack configuration file

Fix trove guest confing to ignore user os_admin

This value of ignore_users in the guest config needs to be set
correctly to ignore the local os_admin user for the trove functional
tests to pass in a devstack-gate environment.

Add architecture to tempest configuration

Cirros may be also built in other architectures other than
x86_64 (ex: ppc). This option should be broader,
so adding a new variable CIRROS_ARCH

Implement Ceph backend for Glance / Cinder / Nova

The new lib installs a full Ceph cluster. It can be managed
by the service init scripts. Ceph can also be installed in
standalone without any other components.
This implementation adds the auto-configuration for
the following services with Ceph:

* Glance
* Cinder
* Cinder backup
* Nova

To enable Ceph simply add: ENABLED_SERVICES+=,ceph to your localrc.
If you want to play with the Ceph replication, you can use the
CEPH_REPLICAS option and set a replica. This replica will be used for
every pools (Glance, Cinder, Cinder backup and Nova). The size of the
loopback disk used for Ceph can also be managed thanks to the
CEPH_LOOPBACK_DISK_SIZE option.

Going further pools, users and PGs are configurable as well. The
convention is <SERVICE_NAME_IN_CAPITAL>_CEPH_<OPTION> where services are
GLANCE, CINDER, NOVA, CINDER_BAK. Let's take the example of Cinder:

* CINDER_CEPH_POOL
* CINDER_CEPH_USER
* CINDER_CEPH_POOL_PG
* CINDER_CEPH_POOL_PGP

** Only works on Ubuntu Trusty, Fedora 19/20 or later **

Fix cinder volume type creation and rename variable

Commit 7062b12b9b91a1eb405d7079c62b62b0de59109f introduced
a bug where the default_volume_type is set to 'lvm' but
that is not the volume-type that's actually created, that
is 'lvmdriver-1' in gate runs, so we see a ton of
VolumeTypeNotFoundByName for the 'lvm' volume type in the
cinder-api logs.

This simply sets the default_volume_type to the volume
type that's created in the create_volume_types function.

Also renames the default_type variable to default_name to
be consistent with variable naming in the rest of the
cinder script.
