Bug Description

Currently there are two storage supports for mysql: Volume and root partition. There is a flag in the conf file that toggles between these two type of storages: reddwarf_volume_support

What we also need is a way to store mysql in a ephemeral drive. The instance would boot with a flavor that specify a ephemeral storage size, which would then appear as another partition and be mounted to /var/lib/mysql.

When an instance is booted with a flavor that contains a ephemeral, the device will appear as 'vdb' just like cinder volumes.
