automatic tagging of docker images and integration test fixes

[dmcwhorter-ddl]

This change does the following:

1. Updates the domino-build.sh script with a new autotag flag (-a) that, when enabled, automatically creates a docker image tag matching the git tag for the latest commit, if it exists.
2. Updates the CI settings to enable the autotag flag. The result is that updating the the base OS for a given docker tag can be accomplished by simply re-triggering a CI build of the git commit for a release with a corresponding git tag.
3. Makes the integration tests run again. They probably still won't be totally predictable or stable. It also disables the tensorflow model that's a part of the integration tests because our RabbitMQ server doesn't support the raw format it uses.
4. Disables most of the seldon github actions workflows that don't work correctly on our fork. The exception is the lint and test steps for the executor and operator.
