While working on an implementation of TLD-specific logic, it was realized that the extra logic methods would need access to the flow's HistoryEntry, so that things like poll messages could be parented properly.
Also, the update flow had not been fixed to perform the fee check.

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.

This CL adds the hooks necessary to implement TLD-specific flow info and update flow logic. Usage of the hooks follows in a separate CL.
