Support for authenticated registry

[raphink]

It seems the current version does not support authenticated registries (using an auth token server).

@raphink - You may be right.

Currently, the tool has been tested with Basic Auth based Registry. I could change it to support auth token server.

Which version of Docker Registry are you currently using ?

[raphink]

I'm using registry:2 with cesanta/docker_auth as the token server.

Hi @raphink just saw this. I'm also experimenting with cesanta/docker_auth, and just starting adding this support (it's currently missing the re-encryption of the token, last step I believe). Did you ever accomplished this?

[raphink]

@ntavares no I didn't. I'd still welcome it though.
