Automatically create password for user

[ScottG489]

Although the user is created, it isn't given a password. The documentation currently instructs the user to manually log in and set the password themselves. However, ansible has the ability to set the password on the user as seen here:

https://docs.ansible.com/ansible/latest/modules/user_module.html#parameter-password

The value of the password should be created using the following command.

openssl passwd -salt abc -1 12345

Where "12345" is the password. The value of the salt can be basically anything. I suppose pick a sufficiently random string but I'm not sure it's too important.

The documentation also currently mentions that you need to log in and manually set the password. This documentation should also be updated. At the time of this writing it can be found here in the README:
