[AETHER-544][AETHER-523] Improve versioning of `tost` docker image and simplify build workflow
VERSION file is used for the release/tag process of `tost`.
Makefile.vars file defines the stable versions of each component
to be used during the build process.
Dockerfile.tost defines a docker label for each component
and uses the *_VERSION vars to set the docker labels.
Moves build logic inside app-build.sh. Build process is stopped if there are pending
changes in the repositories
Adds check-scripts target for shellcheck verify
Add fetch targets to update the repos
Deprecates the use of git-review for git fetch ref/changes/
Updates README to explain the new build process
