feat(workers): add Worker.get_worker_id [NET-523]

[justprosh]

Description

Provide a non-throwing method to get worker peer id.

Motivation

We often call Worker.get_peer_id on decider spell to check whether or not a worker exists, but this method throws an error in the absence of a worker, which pollutes nox logs:

2023-08-16T17:34:28.579229Z  WARN tokio ThreadId(09) aquamarine::particle_functions: Failed host call "worker" "create" ["0x254fb741db88469b152d30f09396779d02cb7be6"] (146us 875ns): "Error: Worker for 0x254fb741db88469b152d30f09396779d02cb7be6 already exists\nWorkerAlreadyExists { deal_id: \"0x254fb741db88469b152d30f09396779d02cb7be6\" }" particle_id="spell_86b9e58f-0385-4247-a8a1-84e8ae546b58_1"

Proposed Changes

Implement Worker.get_worker_id:

service Worker:
  get_worker_id(deal_id: ?string) -> ?PeerId

Worker.get_peer_id will be deprecated soon.
