Subject: store/load offline docker images

JIRA: DOVETAIL-423

usage:
1.cd ${DOVETAIL_HOME}/dovetail/utils/offline
2.edit config.yaml as needed
3.on onsite host, <python download.py>  --> save docker images to defined path
4.on offline host, <python load.py> ---> load docker images to offline env
5.this can be easily extended to other images beside docker images
