WIP: Bull 1520 - pull directly from Keycloak via KC Client
This MR will remain WIP until we get a Keycloak Client to use. In the meantime, it can be reviewed and tested locally (see the Optional Keycloak Integration
section of the README).
This MR will enable LB-BE to query Keycloak for users, groups, and group membership. This KC data is then mapped to LB users, teams, and team membership.
Other fixes:
- Fix use of
IS_LOGGING
variable (it wasn't actually being sent to the sequelize instance)
