Setup separate environments on Redmond.ai box

[mrcabbage972]

It's currently difficult to work on the box because it has a single user with a single environment, which frequently gets broken.

To solve it, we should either create separate users or install docker.

So the way to create users is:

1. login as the ubuntu user
2. sudo adduser [user name]
3. sudo passwrd [user name] - will prompt for the password
4. su - [user name] - will switch the current session to the user
5. whoami - to verify that the new user is indeed active

On the merging server (Seperate machine) we also use a shared account, but there anyone who wants to deviate from the default packages is expected to make a personal conda env. This can be desirable to adopt if you do want shared file access.
