feat: declare the SNMP health OIDs instead of collecting them (0.2.0)

The driver no longer collects over SNMP. SNMP_HEALTH_PROFILE states
where the switch publishes uptime (TimeTicks), CPU and memory (tables
with one row per stack unit, first row as before); the application
polls and computes (napalm-device-types docs/STRUCTURE.md).

Interface counters now come from the 64-bit ifXTable where the switch
has it, as the application reads them for every device.
