VED-811 (Child of VED-720) Refactor PR and Release pipelines to move to GH Actions

[dlzhry2nhs]

Summary

• Routine Change

• PR Deploy and Test pipeline added to Github Actions: this will deploy the AWS backend and create the MNS subscription for PR environments on creation and pushing to the PR. It then executes tests against internal-dev PR and sandbox.
• Continuous Deployment pipeline added to Github Actions: this will run after merging to master and replicates the deployment that was previously in Azure to promote the latest to internal-dev, int, and ref. Tests will also be run.
• Removed all Azure Devops logic except for pipelines that will deploy and test the sandbox, and deploy the proxies. Everything else, i.e. backend deployment, testing will reside in Github Actions.

Reviews Required
