ddev doesn't force writing github uname and token to config file

[iliakur]

What does this PR do?

Lets us set github username and token using only envvars without forcing us to have them in config.toml.

Motivation

I'm fed up with having to set this in the config.toml file every time. Also, security is pushing away from storing credentials in files.
