Create vault-config management script

[dincho]

Current implementation although pretty simple is implementation in the Makefile which is cumbersome to work with and hard to debug and change.

Since the new configuration structure has been implemented it led to a lot of issues.

The new script should abstract the configuration structure and workings. It should implement:

• dump a configuration to a file/dir so it can be used with local ansible playbooks
• update a configuration from a local copy
• bulk dump
• bulk update
