Allow to use trust-dns

[astoycos]

Add options to oci-distrobution to use
non local DNS, mainly for when
running embedded in a docker container.

I don't think the failing CI is part of this :)

[astoycos]

If I get a chance I'll investigate further

I don't think the cargo deny is related, but the build test might be. I'm a bit busy this week but will try to get to debugging it a bit

[astoycos]

Ran this all locally and things were working, pushed again to re-trigger actions

Was the error in the unit tests the first time

@astoycos Sorry for the late response. I've looked into the failures and fixed them with some commits.

I'll let the test run and, if everything is green, I'll merge the PR

[flavio]

All green!

Thanks @flavio!
