NetworkAdapter: add support for Network Adapter Port Metrics

This patch enables support for Nvidia ConnectX network cards. Network
adapter schemas are restricted to a single URI path format:
/redfish/v1/Chassis/{ChassisId}/NetworkAdapters/{NetworkAdaptersId}/.
[1]

And thus, the port URI follows this structure
/redfish/v1/Chassis/{ChassisId}/NetworkAdapters/{NetworkAdaptersId}/
Ports/{PortId}.
[2]

Route handler for collections and each individual components are added
in this patch for each URI resource under
/redfish/v1/Chassis/{ChassisId}/NetworkAdapters.

Association between Chassis and NetworkAdapter is `containing` and
`contained_by`. Association between NetworkAdapter and Port is
`connecting` and `connected_to`.

This patch enable support for following properties for Port Metrics URI
of a Network Port. [3]
- TXBytes
- RXBytes
- RXMulticastFrames
- TXMulticastFrames
- RXUnicastFrames
- TXUnicastFrames
- RXBroadcastFrames
- TXBroadcastFrames
- RXFCSErrors
- RXFrameAlignmentErrors
- RXFalseCarrierErrors
- RXUndersizeFrames
- RXOversizeFrames
- RXPauseXONFrames
- RXPauseXOFFFrames
- TXPauseXONFrames
- TXPauseXOFFFrames
- TXSingleCollisions
- TXMultipleCollisions
- TXLateCollisions
- TXExcessiveCollisions

The patch uses "xyz.openbmc_project.Metric.Value" Interface for Network
Port Metrics properties. Association between a Metric and a Port is
`measuring` and `measured_by`.
