Fix agent node id + randomize offset id (#625)

* Fix agent node id + randomize offset id

- fixes the node_id value
- randomizes a constant offset for the id.handle values
- switch to using node ids in rocprofiler-sdk-tool library
- update tests related to agents

* Logical node id

- sequential node id values from 0 to (N-1) where N is the number of agents
