feat: enable remote pilot logging system

[martynia]

Enable remote logging system with open search. This PR only shows a router in its preliminary form. The router needs access to PilotAgentsDB (#292) to get a pilot ID from a pilot stamp.

@chrisburr I think we need a pilot logging router, even in its basic form. One of the tests fails because it is missing.

@chrisburr What is a reason of test failures here ? The demo runs fine locally, can be contacted with a client etc. The test fails with dirac login, waiting for diracX to be installed. Could it be that I missed a setting somewhere ? The failure is persistent.

@chrisburr @chaen
I managed to reproduce the problem locally. There is the same failure on GitHub and locally. Since the demo runs fine (the DB is there), is it possible that integration tests fail (NotImplementedError: Cannot enable system_name='pilotlogs' as it requires missing_os_dbs={<class 'diracx.db.os.pilot_logs.PilotLogsDB'>} because of charts being no discoverable by the CI workflow ?

This type of error occurs (in the demo) where charts don't list a relevant DB

Both local and CI tests reach the same point - server installation failure.
