main branch should use different version from the releases

[amohamed1]

When building from main, the version should include -main or/and GIT_COMMIT_ID-dirty
to make sure users don't get confused which version they are using. Today, if a user
clones the git tree, build the binary and replace ocm-cli in a running system it will look
like they installed/deployed the version 0.1.60 (based on ocm-cli version). Which is not true.
Of course, sysadmins can always check the sha256 from the binary but it's hard to assume steps
for all people/orgs.

Example:

Cloning

$ git clone https://github.com/openshift-online/ocm-cli.git && cd ocm-cli
