Update for DockerHub

[morehavoc]

We are pushing these to the EA docker hub now, so update this Repo with the correct tag names and scripts.

• EANginxUwsgiBase => ea-base will become earthadvantage/py-base
• EASSHBase => ea-ssh-base will become earthadvantage/py-ssh-base (since it builds on the other)

In other docker files you will want to replace the line:

FROM ea-base with FROM arthadvantage/py-base:tagname where tag name is one of:

• latest - Always the most current build
• V1.0.0 - Or another specific version

I might also include tags for the underlying image to show what version of that we are connected to, like node-1.18-20.04_edge
