This patch supports CLI of vnflcm v2 APIs which are added in Yoga
release.
They are as follows.
* vnflcm update
* vnflcm scale
* vnflcm heal
* vnflcm change-ext-conn
* vnflcm op fail
* vnflcm op retry
* vnflcm op rollback
They are common with v1 except heal. An optional parameter
'--additional-param-file' is added to heal CLI.
