I want to know container nodes before create a container to check that policy meets my expectations.

netmap view-policy?
Or, maybe a flag to container nodes which takes a policy?

The problem is that we cannot know for sure without a container ID, but we can build an approximation.

In technical terms, this involves creating a container structure locally without adding the result to the container contract. The placement vector is computed using the most recent network map.

If the generated output meets the necessary requirements, the container must be produced precisely the same way, with the Nonce and Timestamp fields included to obtain the same resulting ContainerID. This process adds an interactive dimension to the command.

@anikeev-yadro @realloc is the policy-playground command in #416 sufficient for closing this? or do we want some additional tooling?
