GitHub Action: Workflow Run Queue

If the same workflow is already running from a previous commit, wait for it to finish

Why?

Workflows run on every commit asynchronously, this is fine for most cases, however, you might want to wait for a previous commit workflow to finish before running another one, some example use-cases:

Deployment workflows
Terraform workflows
Database Migrations

Usage

`.github/workflows/my-workflow.yml`

jobs:
  xyz:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2
      - uses: ahmadnassri/action-workflow-queue@v1

      # only runs additional steps if there is no other instance of `my-workflow.yml` currently running

Inputs

`timeout`	❌	`600000`	timeout before we stop trying (in milliseconds)
`delay`	❌	`10000`	delay between status checks (in milliseconds)
