session: improve cli
Type: feature
Allow session cli filtering based on thread index, transport protocol,
session state and range of session pool indices. For instance
show session thread 1 proto tcp state ready range 0 20 verbose
Shows the session ids for the first 20 tcp sessions in thread 1 that are
in ready state.
To avoid excessive output that could reasult in the worker barrier being
held by the main thread for long periods of time, the session cli will
only output:
- session ids (verbose == 1) for a maximum of 50 sessions / worker
- verbose > 1 details for a maximum of 10 sessions
