bonding: T5254: Fixed changing ethernet when it is a bond member

If ethernet interface is a bond memeber:
  1. Allow for changing only specific parameters which are specified
     in EthernetIf.get_bond_member_allowed_options function.
  2. Added inheritable parameters from bond interface to ethernet
     interface which are scpecified
     in BondIf.get_inherit_bond_options.
     Users can change inheritable options under ethernet interface
     but in commit it will be copied from bond interface.
  3. All other parameters are denied for changing.

Added migration script. It deletes all denied parameters under
ethernet interface if it is a bond member.
