Not a fan of changing the CLI contract without some attempt to accommodate "legacy" (we just went 1.0, heh) usage. 🤔

[amartin120]

Okay. After some good conversation with @dweomer, I'd like to re-work this a bit.

hauler login <url> --login-type (helm or other options down the road)

default to registry if --login-type is omitted to not break any existing cli contracts.

In order for this to work without even more helm specific flags, I'll need to work some non-trivial things out. Mostly around how the "repo name" plays into the equation.

Hey @amartin120, what is left to complete the rest of this PR?
