Add version

[aufi]

Adding tool version to CLI that should return version number and commit hash. Usage: kantra version.

The version can be setup when building the kantra, example:

$ go build --ldflags="-X 'github.com/konveyor-ecosystem/kantra/cmd.Version=1.1.1' -X 'github.com/konveyor-ecosystem/kantra/cmd.BuildCommit=$(git rev-parse HEAD)'"
$ ./kantra version
version: 1.1.1
SHA: 75daa9736c52e85cad832d1cd2eb95d2d98dad8e

The default development version 99.0.0 follows operator and UI convention.

Fixes: https://issues.redhat.com/browse/MTA-2201

@djzager @fbladilo Hi, would it be possible set the CLI tool version with ldflags on build or is it needed to use another way? Thanks!

For the upstream:

1. Update the Dockerfile go build(s) that takes the version/git as ARG
2. Update the workflow that passes the version stuff along to the build step.

I will defer to @djzager on this one, once he is happy that this doesn't break the build system the new command looks fine to me

Thanks David! Arguments were added to Dockerfile and workflows. The VERSION should be read from tag in release-tools build env and the BUILD_COMMIT is set to env using pre_build_cmd.
