   `./breeze -i kerberos` should give you a docker env with kerberos set up I think.
   
   From CI on this branch:
   ```
   18.85s setup    tests/api/auth/backend/test_kerberos_auth.py::TestApiKerberos::test_trigger_dag
   ...
   0.09s call     tests/api/auth/backend/test_kerberos_auth.py::TestApiKerberos::test_trigger_dag
   ...
   0.01s teardown tests/api/auth/backend/test_kerberos_auth.py::TestApiKerberos::test_unauthorized
   ...
   0.01s call     tests/api/auth/backend/test_kerberos_auth.py::TestApiKerberos::test_unauthorized
   =========== 37 passed, 8032 skipped, 8 warnings in 185.60s (0:03:05) ===========
   ```
   
   Compared to on master:
   
   ```
     31.00s setup    tests/api/auth/backend/test_kerberos_auth.py::TestApiKerberos::test_trigger_dag
     25.11s call     tests/executors/test_celery_executor.py::TestCeleryExecutor::test_celery_integration_1_redis_redis_6379_0
     20.30s call     tests/executors/test_celery_executor.py::TestCeleryExecutor::test_celery_integration_0_amqp_guest_guest_rabbitmq_5672
     10.97s call     tests/api/auth/backend/test_kerberos_auth.py::TestApiKerberos::test_trigger_dag
     7.16s call     tests/providers/trino/hooks/test_trino.py::TestTrinoHookIntegration::test_should_record_records
     6.03s call     tests/api/auth/backend/test_kerberos_auth.py::TestApiKerberos::test_unauthorized
     =========== 37 passed, 8179 skipped, 8 warnings in 287.80s (0:04:47) ===========
   ```
   
   So saves about a minute for the "integration" set of tests.
   
   We probably need to optimize the "slow" path next -- which ever of the test groups on master is the slowest -- since they are run in parallel one test type being quicker might not help anymore if we are always waiting on a slow one.
