What this PR does / why we need it:

This PR adds support for skipping handler registration and QoS manager initialization based on configuration in Volcano Agent, which is needed when the user only need a set of feature, and cannot enable some feature as they cannot run it on specified OS.

  1. If a feature is not listed in supported-features, skip the registration of its corresponding handler.
  2. If networkQoS is not in supported-features, skip the initialization of the QoS manager.
  3. If the QoS manager is not initialized, skip its health check.
