Two tests rely on Kea getting configured with the old configuration from file after being sent a config-set
with new configuration and after being restarted. These tests failed for me because when generating the new configurations for config-set
they were also sent to the server overwriting the old file. The two tests are:
- test_control_channel_http_after_restart_load_config_file
- test_control_channel_http_test_config
