Create dev containers for services

[faucomte97]

The codeforlife-portal-react, codeforlife-workspace and the codeforlife-sso dev containers do not have a postCreateCommand because these services have a run script which install the dependencies and runs a local server - I feel like this should be done by the developer manually, otherwise it might be confusing.

The codeforlife-deploy-appengine dev container does not have a postCreateCommand because the project doesn't have properly defined requirements / dependencies.
