Print Version Number on startup (#1659)

* Changed Dockerfile to get the Enviroment variable from the github actions workflow and pass it to the main.go file

Added a function in main.go to fetch the enviroment varible and to have a fallback if the env variable isnt there

Added a test for the version to use for this branch only

* Update test-version.yaml

* Update test-version.yaml

* Removed the test because its not needed when we push upstream

* Moved the version print in main.go to the Log codeblock as requested by toast-gear

Added version as issue#1161 requests.

Decided to use a docker tag structure for the userAgent string, with : being a seperator of the name and version

* Used ldflags instead like mumoshu recommended

Changed Dockerfile to use $VERSION from the workflow

Added version.go and the build package
Removed the getVersion function as we can just get the value directly

* * Removed the default from the go code (set it as N/A)
* Changed version from latest to dev inside makefile
* Added buildarg for version to the dockerfile in the makerfile
* Added VERSION with default dev value as arg inside dockerfile
* Cleaned up inside dockerfile

* Fix failing test

* Fix possible missing VERSION in the ARC UA suffix due to missing build arg in docker-build-push step
