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.

Ephemeral volume support

This feature enables reddwarf to create instance and run mysql on ephemeral disk.
To enable this feature, set the flag "reddwarf_volume_support to False and specify the device_path and mount_point variables.

Also added int tests for ephemeral support
