Introducing BandwidthProfileConfigBehaviour to manage policers/markers

- Creating BandwidthProfile Class to represent generic policers/markers
- BandwidthProfile can be Single/Two Rate, Two/Three Color depending on parameters
- Including fromMeter() method to convert a Meter into a BandwidthProfile
- Adding unit tests for BandwidthProfile class
- Creating BandwidthProfileAction class to represent a color (green/yellow/red) action
- BandwidthProfileAction allows remarking one of: DSCP class, IP precedence, Drop precedence
- Adding unit tests for BandwidthProfileAction class
- Creating DscpClass and IPPrecedence Enums and unit tests in org.onlab.packet
- Adding kBps/MBps/GBps methods in org.onlab.util.Bandwidth class
