BDD: Configure CI to run BDD tests

[tk3369]

Configure CI to run BDD process (pull feature files, install Grakn, and execute the tests)

Here's what I think would work:

1. Create a GitHub action to set up Grakn server
2. Create a GitHub action (or reuse an existing if available) to clone the BDD repo with feature files
3. Write a test script that execute the feature files using ExecutableSpecifications.jl

As a developer, the local environment should have Grakn server and features available already. Then, doing ] test from the REPL should just include BDD tests.

Perhaps we can use this here: https://github.com/marketplace/actions/github-action-for-bash

I created a GitHub Action here: https://github.com/Humans-of-Julia/GraknRunner

Not sure yet, if we can do it all in one, but would be ideal I think.

It can be easily included in a workflow file like:

name: Grakn BDD runner
on: [push]

jobs:
  hello_world_job:
    runs-on: ubuntu-latest
    name: A job to pull feature files, install Grakn, and execute the tests
    steps:
    - uses: actions/checkout@v2
    - id: foo
      uses: Humans-of-Julia/[email protected]
      with:
        who-to-greet: 'Mark'
    - run: echo random-number ${{ steps.foo.outputs.random-number }}
      shell: bash

I'm curious here, would that mean the test has to run locally? Wouldn't it be cool to let it all run in the virtual machine in the GitHub Action runner?
