Symfony 4.x+ Harness for Workspace

To use this harness:

1. Install Workspace
2. Run ws create <projectName> inviqa/symfony:v1.5.2
3. Fill in project-specific AWS and Github credentials, set as blank if you don't need them
4. Change to the directory: cd <projectName>
5. Create an initial commit, ensuring that workspace.override.yml is not added to git:

git init
git add .
git commit -m "Initial commit"

6. Store the workspace.override.yml contents in a suitable location (such as LastPass).
