build: move to circle ci

[dmccaffery]

• migrate to circleci for automated build and deployment
• execute prompt install and a single prompt command to smoke screen the installation:
  • macos
  • ubuntu
  • fedora 29/30
  • debian
  • centos
  • mint
• update readme to include thank you to circleci and a build status

Closes: #23

@sjk07 : added smoke test for all supported platforms if I can get your review?

[sjk07]

saw this b4 and the builds didn't pass yet, but looks like we are are good now.

LGTM!

yeah; @sjk07 : I had to create custom docker files to install the bare minimum prerequisites on each of the platforms, namely sudo and locales. In addition, brew refuses to install as root, so I needed to add a custom user and add it to sudoers without a password requirement in order to get this to run within docker. Its as close to real-world as I can get.
