Currently EapFee is a separate class that has no inheritance from either
BaseFee and Fee. With this CL its functionality is merged into the Fee class
and the type of the fee can be identified by the FeeType enum in the Fee class.
Future custom fees can follow the same pattern.

This CL enhances various domain flows (check, create, delete, renew, restore, transfer, update) so that they invoke the appropriate methods on the object implementing the TLD's RegistryExtraFlowLogic (if any). TldSpecificLogicProxy is also updated to invoke RegistryExtraFlowLogic proxy (if any) to fetch the appropriate price. The tests use a made-up extra flow logic object which can be attached to a test TLD to make sure that the proper routines are being invoked.
