Fauxton depends on CouchDB (and eventually an IdP) to work. This suggests a .devcontainer makes sense. Proposed features:

• runs Fauxton
• runs CouchDB
• optional, based on an .env variable runs keycloak as IdP
• CouchDB & keycloak are fully transient, clean on each start
• Scripts initialize keycloak and CouchDB to a known state

If that's acceptable (please comment) I will provide an implementation in a PR
