Feature Request: Add Optional publish Stage to tf-dev-env

Summary

Introduce an optional publish stage in container/run.sh to support pushing built container images to a custom/external registry.
This stage runs only when explicitly enabled via environment variables.

Problem

tf-dev-env currently does not provide a built-in way to publish images to external registries.
Users must manually re-tag and push images after a build, which is inefficient and error-prone.

Proposed Solution

Add a conditional publish stage that:

• Runs only when CONTRAIL_REGISTRY_PUSH is defined
• Re-tags built images to the target registry
• Performs docker login when CONTRAIL_REGISTRY_USERNAME and CONTRAIL_REGISTRY_PASSWORD are provided
• Pushes images automatically
• Skips the stage when not configured

Example Usage

export CONTRAIL_REGISTRY_PUSH="my-registry.example.com"
export CONTRAIL_REGISTRY_USERNAME="myuser"
export CONTRAIL_REGISTRY_PASSWORD="mypassword"

./run.sh build


There are stages available to run ./run.sh <stage>:
  build     - perform sequence of stages: fetch, configure, compile, package, publish (if configured)
              (if stage was run previously it be skipped)
  fetch     - sync TF git repos
  configure - fetch third party packages and install dependencies
  compile   - build TF binaries
  package   - package TF into docker containers (you can specify target container to build like container-vrouter)
  test      - run unittests
  freeze    - prepare tf-dev-env for pushing to container registry for future reuse by compressing contrail directory
  upload    - push tf-dev-env to container registry
  publish   - push built containers to custom registry (requires CONTRAIL_REGISTRY_PUSH)
  none      - create the tf-dev-env container empty
  frozen    - fetch frozen tf-dev-env from Ci registry, you still have to use run.sh or fetch/configure to get sources
  doxygen   - builds doxygen documentation for the project

Possible Solution: https://gerrit.opensdn.io/c/opensdn-io/tf-dev-env/+/2419

[mkraposhin]

Lets rename "CONTRAIL_REGISTRY_PUSH" to "OPENSDN_REGISTRY_PUSH" , CONTRAIL_REGISTRY_USERNAME to OPENSDN_REGISTRY_USERNAME, CONTRAIL_REGISTRY_PASSWORD to OPENSDN_REGISTRY_PASSWORD

[mkraposhin]

Oh, and TF should be also substituted with OpenSDN.
