Description

Since the new RuncContainerRuntime will be using a lot of the same code as DockerLinuxContainerRuntime, it would be good to move a bunch of the DockerLinuxContainerRuntime code up a level to an abstract class that both of the runtimes can extend.

The new structure will look like:

OCIContainerRuntime (abstract class)
  - DockerLinuxContainerRuntime
  - RuncContainerRuntime

This JIRA should only change the structure of the code, not the actual semantics
