Jerin Jacob d04fb3b55c ethdev: add protocol based meter input color selection
Currently, meter object supports only DSCP based on input color table,
The patch enhance that to support VLAN based input color table,
color table based on inner field for the tunnel use case, and
support for fallback color per meter if packet based on a different field.

All of the above features are exposed through capability and added
additional capability to specify the implementation supports
more than one input color table per ethdev port.
