ci: automate image build and tag

[lampajr]

Fixes https://issues.redhat.com/browse/RHOAIENG-3433

Description

Automate the MLMD container image build, push and tag on every master branch push

How Has This Been Tested?

Workflow tested locally using act extension by running:

gh act -s GITHUB_TOKEN=$GITHUB_TOKEN -s QUAY_USERNAME=$QUAY_USERNAME -s QUAY_PASSWORD=$QUAY_TOKEN push

Here the pushed images: https://quay.io/repository/alampare/mlmd-grpc-server?tab=tags

NOTE: If you want to try this remember to change the QUAY_ORG env variable to point to your personal quay repository and to export QUAY user/pwd.

Merge criteria:

• The commits are squashed in a cohesive manner and have meaningful messages.
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has manually tested the changes and verified that the changes work
