+ Ethdev, , mempool and telemetry maintainers

All of the above data except[1] is generic data that can be derived
from ethdev APIs or ethdev data from lib/ethdev itself,
IMO, We should avoid duplicating this in driver and make useful for
other driver/application by adding generic endpoint in ethdev.
Same comment for "[2/4] mempool/cnxk: add telemetry end points" for
mempool subsystem.

Thoughts from Maintainers?

  uint8_t ptype_disable;
  bool scalar_ena;
  bool ptp_ena;
  uint16_t flags;

Not a maintainer of those libs, but +1 to making anything generic that can
be, save reimplementing things multiple times in drivers.

I agree, I feel it would make more sense to have most of the job done in the
mempool library in generic. A new ops could be added to fill driver-specific
info.
