Adds ability to capture and image hosts

JIRA: PHAROS-322

Adds the action metadata files, action code, and workflow definitions
that allows us to image a selected host with any disk image or operating system.

For example, to install ubuntu on host "pod4", run

	st2 run pharoslaas.fog_imageWorkflow host=pod4 os=ubuntu
