Is your feature request related to a problem? Please describe.
We have been using a client that was released in Nov/2022:

rucio-clients~=1.29.10

and there has been many other releases since then.
So we should definitely look into updating, which will likely bring in other updates as well, like the chryptographic library and others.

Describe the solution you'd like
Update rucio-clients package to (one of) the latest stable releases, maybe 34.4; but we might as well quickly touch base with the DM team to see if they have any suggestion on this update.

This update involves at least:

• updating the requirements.txt in WMCore
• building a new (test) image
• running the DMWM set of test workflows
• and ensuring that everything works properly (including a container level rule made by RucioInjector).

This will also affect central services, so whenever it gets deployed in dev/testbed, we better keep an eye on the microservices interfacing with Rucio.
