The configureUserSettings field contained nginx configuration
('http2_push_preload on;') which was incorrectly being used as
CONFIG_OVERWRITE_JSON. This caused harbor-core to crash with a
JSON parse error.
CONFIG_OVERWRITE_JSON expects valid JSON for Harbor configuration
overrides, not nginx snippets. Removing this field to fix the
CrashLoopBackOff.
