F convenient admin

Summary

This MR adds a few convenience features to caosdb_admin:

• Allow activating users directly after creation.
• Allow setting a password on the command line.

This is important for allowing automated scripts to batch generate passwords and users.

Focus

I updated the documentation in argparse and hope that it matches the programming logic exactly. Please check.

Test Environment

Just check out this branch and create a user in an instance of your choice, e.g. using: python3 -m caosdb.utils.caosdb_admin create_user username email password
