get_health_metrics, get_ssids, get_radio_info and get_wireless_clients
only raised NotImplementedError. They are left over from when the
driver sat on AccessPointDriver, and a stub makes a capability check
(callable(getattr(driver, name))) answer yes. The application polls
SNMP itself (napalm-device-types docs/STRUCTURE.md); a phone has no
profile to declare.
Also stops tracking the .pyc and egg-info files .gitignore already
lists.
Closes#2
