More vitual project tidbits...

[marcmengel]

In the daemon that talks to Rucio, we should ignore virtual projects; no point running off and getting info about
the files from rucio if we aren't using it.

I think that would be about here:
https://github.com/fermitools/data_dispatcher/blob/main/daemon/daemon.py#L469
we would just do
if project is not None and not project.attributes.get("virtual", False):
instead of
if project is not None:
so we wouldn't start a thread to get info from Rucio for that project.

Also here:
https://github.com/fermitools/data_dispatcher/blob/main/web_server/data_server.py#L344
in project(), we should only get replicas if they asked for them and the project is not virtual...
