Adds Docker based build system for Binary Packages, CI/CD, Smoke Testing and Development. (#7735)

* Added Dockerfile for building, packaging and performing basic smoke tests of the package(s) and NetData Agent itself

* Moved install of package per distro into a script and refactor in order to supprot other distro(s)

* Add support for RPM based systems too (Fedora, CentOS)

* Drop the unnecessary (for now) Debian cleanup steps

* Reverse the order of installing NetData agent and testing tools

* Update default VERSION to 0.1 to match builder images

* Added support for openSUSE

* Minor fixes from review

* Update Dockerfile

* Update Dockerfile

Co-Authored-By: Austin S. Hemmelgarn <ahferroin7@gmail.com>

* Move thigns around a bit

* Re-update test/install shell scripts to be POSIX. We don't really want to depend on Bash here

* Fixed support for yum vs. dnf

* Fixed paths to scripts

* Added a script to kick off the build/package/install/test flow more easily for both humans and CI/CD
