feat(logging): add localIP and Cache fields to HTTPRequest conversion from proto (#3600)

Fix #3588 

Changes: 
- Turned integration test back on for `logadmin`. According to previous comments, this may be flakey so I will closely monitor and debug. 
- Added fields LocalIP, CacheLookup, and CacheFillBytes back to httprequest conversion from proto to logging.httprequest
