fix(staged-dockerfile): do not store non-target Dockerfile stages in …
Browse files Browse the repository at this point in the history 
…the final-repo

* Do not store non-target Dockerfile stages in the final-repo, nor set custom tags on non-target stages.
* Changed staged-dockerfile builder digest calculation algorithm: do not use instruction number in digest input calculation, only instruction name.
