[COR-175] Image build and upload

[sjmiller609]

This is the plan for our release automation:

Image workflow (on commit to any branch): This PR is only handling this part

• Publish docker image with git hash as tag
• If main or release/** branch, also publish the version in cargo.toml, if the file is present
• If main branch, also publish ‘latest’

Below items in following PRs

Cargo workflow (on commit to main or release/** branch):

• publish cargo projects that are not already published (i.e. skip publish when version in Cargo.toml already exists on crates.io)

Github release workflow (on commit to release/** branch):

• github release for the major.minor version in the branch name, lowest unused patch number
• in release note, list versions of subcomponents

On PR to main or release/** branch:

• For changes in Cargo projects, fail if the version in Cargo.toml is already is published

did not end up consuming this feature in a workflow, but might as well leave it in case we want this flag later.

This step finds directories with Dockerfiles, filtering for only those that are changed. In the case of main branch or release branch, it provides all directories with a Dockerfile. In following PR, want to move this into an action and also reuse the logic for Cargo.toml files in order to take action only when a particular crate changed.

this change consolidates all image build workflows.
