adding Vm state save script (#4)

* added vm-state script

* added nerc openstack credential secrets

* updated backup.sh to run vm save python script

* rolled back the cron to run once per day

* removed last blank line

* cron will run once per hour

* addeed a script to compare current state to a state in json save file specified

* cleaned up eof blank line, renamed vm-state to vm-save because it seems to make better sense.

* updated Docker file to include new openstack-vm scripts

* simplified to use openstack shell commands instead of python script and moved restore script out of this repo
