[GONRG-6174] DF Release Pipeline improvement

Sample pipeline: https://community.opengroup.org/osdu/platform/deployment-and-operations/infra-gcp-provisioning/-/pipelines/167209

Refactoring of release pipeline that is used for partially automating DF release.

Conditions to run:

• Running on release branch with SHORT_TAG variable (e.g. 0.19)

How it works:

1. gather-release-information job uses python script to gather information about release status and artifact versions for each service

The output of the job is json with the following format:

...
    {
        "last_release_branch": "release/0.19",
        "last_release_tag": "-",
        "image_tag": "bd27a5fa",
        "helm_version": "0.19.0-release",
        "is_released": true,
        "has_release_tag": false,
        "type": "service",
        "service_name": "indexer"
    },
...

2. modify-release-files job takes output as previous job as its input and modifies release files for both DF

Files modified:

  OUTPUT_TF_DAG_VERSIONS_FILE: "./modules/osdu/inputs_dag_versions.tf"
  OUTPUT_TF_HELM_VERSIONS_FILE: "./modules/osdu/inputs_helm_versions.tf"
  OUTPUT_CHART_FILE: "./helm/osdu-infra-onprem/Chart.yaml"

3. make-release-merge-request job creates MR for release branch with changes to files made by previous job
