fix z series clean logic (file glob match) add add/port logic for pico series device

[tmack8001]

The file glob match used to detect sessions of a machine was not matching filenames appropriately anymore. Ported similar "num_sessions_since_clean" from z into the pico series devices (using comment to decide response format... I don't have a working pico device so can't test).

Tested both z and pico via manually adding files locally and curling the API.
