odp-execute: Add command to switch action implementation.

Browse Source 
This commit adds a new command to allow the user to switch
the active action implementation at runtime.

Usage:
  $ ovs-appctl odp-execute/action-impl-set scalar

This commit also adds a new command to retrieve the list of available
action implementations. This can be used by to check what implementations
of actions are available and what implementation is active during runtime.

Usage:
   $ ovs-appctl odp-execute/action-impl-show

Added separate test-case for ovs-actions show/set commands:
odp-execute - actions implementation
