This is a work in progress to test building on CircleCI (in debug, meaning we remove the --release tag) to see if the build times are shorter. Changes include:

• I've removed the rust library base image in favor of the same base used in azure (ubuntu:16.04) to try and replicate to the best that we can.
• The command to install rust is also taken from azure-pipelines, targeting a specific nightly build
• To control building release / debug, there is a RELEASE build arg. We only add it in the case of a tag/release, otherwise we build debug.

My wireless is out today so I've been developing on a remote instance, which isn't as great as local (so it's a bit slow). I figure it would be quicker / more reproducing of the actual build environment to open the PR and use CircleCI to test the timing. I'm testing a build (with release) on my instance, and we can test the debug build here.

I'm also:

• removing extra dependencies that @jonathandturner mentioned aren't needed
• removing the need for the QUAY_TOKEN in favor of the defaults, and the function to check

And of course, I'll update the PR if needed.
