initial commit whith ceph (rbd) integration

For installation of Fuel with support of ceph-0.61 in Glance and Cinder (throw rdb) you need:

- place such rpms from https://github.com/vizvekov/fuel/tree/master/rpms/
to download.mirantis.com YUM repo
gdisk-0.8.4-1.el6.x86_64.rpm
leveldb-1.7.0-2.el6.x86_64.rpm
snappy-1.0.5-1.el6.x86_64.rpm
qemu-lvm_rbd-1-1.x86_64.rpm # this is rebuilded qemu-kvm with rbd support

- set additional paramreters in site.pp
see for ex. our site.pp file that we used: https://github.com/vizvekov/fuel/blob/master/deployment/puppet/ceph/examples/site_openstack_ha_full.pp

$glance_backend          = 'rbd' # storage type for Glance 

openstack::controller(_ha)
    rbd_user                    => 'admin',   # username for Glance's ceph pool
    rbd_pool                    => 'images',  # name of ceph pool that should be used for Glance
    cinder_use_rbd         => 'yes',          # should we use the `rdb` as Cinder backend
    cinder_rbd_user         => 'admin',       # username for Cinder's ceph pool
    cinder_rbd_pool         => 'volumes',     # name of ceph pool that should be used for Cinder
    cinder_rbd_uuid         => '143b14f0-54ba-4c21-ba11-8b08c 33c5375', # uuid key for libvirt (it's generated by uuid utility, used for generationg of request for additional block devices attaching)

openstack::compute
    secret_uuid                   => '143b14f0-54ba-4c21-ba11-8b08c33c5375',  # uuid key for libvirt, should be the same with cinder_rbd_uuid      
    rbd_user                   => 'admin',  # username for Cinder's ceph pool accessing (rbd pool)
    use_rbd                   => 'yes',  # should we use the rbd?
