Credentials now have a required CredentialType, which defines inputs (i.e., username, password) and injectors (i.e., assign the username to SOME_ENV_VARIABLE at job runtime) This commit only implements the model changes necessary to support the new inputs model, and includes code for the credential serializer that allows backwards-compatible support for /api/v1/credentials/; tasks.py still needs to be updated to actually respect CredentialType injectors. This change *will* break the UI for credentials (because it needs to be updated to use the new v2 endpoint). see: #5877 see: #5876 see: #5805
