Merge pull request #4 from zalando-incubator/disable_teams_api_db_access_flags

Allow disabling access to the DB and the Teams API.

Command-line options --nodatabaseaccess and --noteamsapi disable all
teams api interaction and access to the Postgres database. This is
useful for debugging purposes when the operator runs out of cluster
(with --outofcluster flag).

The same effect can be achieved by setting enable_db_access and/or
enable_teams_api to false.
