Today `atelet` and `ateom` derive the per-actor directories (oci
bundles, runsc state, pid files, checkpoint and restore state,
durable-dir, system-info and volume roots) from the actor UID through
the same package, `internal/ateompath`.
This PR:
1. Add an `ActorDirs` message to RunWorkloadRequest,
RestoreWorkloadRequest, CheckpointWorkloadRequest and
TerminateWorkloadRequest, and have atelet fill it with the directories
it prepared. **The ateoms do not read it yet.**
2. Split `internal/ateompath` into:
- `cmd/atelet/internal/ateletpath`: atelet's pathes, the per-actor
directories (and `ActorDirs`, built from them) plus the directories only
atelet uses.
- `internal/nodepath`: shared pathes, the base dir both mount, the ateom
socket, the OTLP
sockets, and the netns name.
- `internal/ateompath`: what the ateoms still derive from the actor UID,
each function marked with the `ActorDirs` field it duplicates. atelet no
longer imports it.
---------
This is the first part of #1604 to decouple atelet and ateom shared
pathes. Behavior **does not change**: both sides still compute the same
paths, atelet from `ateletpath` and the ateoms from `ateompath`.
Followup PRs will remove ateompath by making `ateom-gvisor` and
`ateom-microvm` read the `ActorDirs` message from RPC.
