1067: Update password in commandline r=hoellen a=hoellen

## What type of PR?

Feature

## What does this PR do?
Adds the ability to set/reset a user's password from the Mailu command line. Similar to the user command:
```
docker-compose exec admin flask mailu password myuser example.net 'password123'
```
With this we can reset the demo server password every few minutes (#987)
