compass: Build Docker images with jjb

JIRA: COMPASS-567

Add compass4nfv-docker.yml
compass-tasks-k8s and compass-tasks-osa are dependent on compass-compass-tasks.
So we have to phase to build docker images
phase 1. execute the multijob 'build compass-tasks images'
Only the phase 1 is successful then excute the phase 2
phase 2. execute the multijob 'build all compass images'

Modify the opnfv-docker.sh
1. Add a function remove_containers_images
2. call the remove_containers_images when beginning and finishing build
   to solve the problem of rmove of images due to dependancy
