In order for us to release a binary, we need to follow a semantic versioning schema to later tag binaries, git tags and RPMs with. Our CLI should print which version it runs on. We start with 0.0.1 as our first scratch release.

We also need a script to bump versions, there is already an example that updates a go variable in https://github.com/openshift/odo/blob/main/scripts/bump-version.sh

AC:

• CLI has a new flag -v / --version that will return 0.0.1 driven by a variable
• there should be a script to bump that version
• add dev.md documentation on releasing like: in https://github.com/openshift/odo/blob/master-backup/docs/dev/development.adoc#release-guide
