Fix req compat

[chaen]

v8.0 requests have OwnerDN and OwnerGroup
v9.0 requests have Owner and OwnerGroup

There was a compatibility layer that allowed processing v8 request on a v9 server. Unfortunately that did not work well with server certificates (used in the ReqProxy for example).

To illustrate it, I created a Request and dumped it to a json file using v8.
I can then load it, and validate it with a v9 server, and you see the Owner and OwnerGroup are wrong

import json
from DIRAC import initialize

initialize()

from DIRAC.RequestManagementSystem.private.RequestValidator import RequestValidator
from DIRAC.RequestManagementSystem.Client.Request import Request

from DIRAC.Core.Base.Client import Client

validator = RequestValidator()

v8_req_json = '{"RequestName": null, "OwnerDN": "/DC=ch/DC=cern/OU=Organic Units/OU=Users/CN=bond/CN=705305/CN=James Bond", "OwnerGroup": "lhcb_user", "Status": "Waiting", "Error": null, "DIRACSetup": null, "SourceComponent": null, "JobID": 0, "CreationTime": "2025-04-11 14:59:34", "SubmitTime": "2025-04-11 14:59:34", "LastUpdate": "2025-04-11 14:59:34", "NotBefore": "2025-04-11 14:59:34", "Operations": []}'

loaded_dict = json.loads(v8_req_json)

print(
    f"{loaded_dict.get('Owner')=} {loaded_dict.get('OwnerGroup')=} {loaded_dict.get('OwnerDN')=}"
)
req = Request(v8_req_json)

print(f"{req.Owner=} {req.OwnerGroup=} {req.OwnerDN=}")


host_credentials = Client(url="Configuration/Server").whoami()["Value"]
validator.setAndCheckRequestOwner(req, host_credentials)

print(f"{req.Owner=} {req.OwnerGroup=} {req.OwnerDN=}")

loaded_dict.get('Owner')=None loaded_dict.get('OwnerGroup')='lhcb_user' loaded_dict.get('OwnerDN')='/DC=ch/DC=cern/OU=Organic Units/OU=Users/CN=bond/CN=705305/CN=James Bond'
req.Owner=None req.OwnerGroup='lhcb_user' req.OwnerDN='/DC=ch/DC=cern/OU=Organic Units/OU=Users/CN=bond/CN=705305/CN=James Bond'
req.Owner='secret.cern.ch' req.OwnerGroup='hosts' req.OwnerDN='/DC=ch/DC=cern/OU=Organic Units/OU=Users/CN=bond/CN=705305/CN=James Bond'

The problem is that once the DB is screwed up, you have lost the group information for good, so you can only guess it.

There might still be a problem when the REA tries executing old requests, but since I don't have any of it anymore in the system, I can't check...
