[RFE] docker client - do not read $HOME/.docker/config.json

[runcom]

it's ugly that a library is retrieving credentials from something on the host w/o users noticing. I think we should find a way to abstract credentials and put them directly on ImageSource initialization

Hum, but the default implementation should still read that file (or whatever docker login sets up), right?

Equally, it would be nice to have a reliable way to run in-process unit tests which do not touch the home directory.

I am currently looking at how parseImage… get their certPath and tlsVerify parameters, which is ugly to pass down into ImageSource. I guess we would benefit from a SystemContext / OuterWorldConfiguration / HereYouCanAskAboutYourEnvironment (all silly names, I know, there must be a better one) structure to create per-process and to pass to the ImageSource/ImageDestination constructors.
