Add UDP ports configuration to IXIA traffic profile

Add UDP ports configuration to IXIA traffic profile

- Implemented handling of UDP source and destination ports from
  IXIA traffic profile.
- UDP ports can be defined as a single value or as a random range.
  Ports range is configured with two parameters 'fixed_bits' and
  'mask_bits'.
- For example '8-48' range definition will create a repeatable
  pattern of four values that fall within the range of 8 and 56.
