WFLY-4152 clean up @deprecated for connector subsystem

removed all SVH and changed OperationFailedException @deprecated constructor
You don't need this variable anymore either. The only reason it's here is to pass it into rollbackRuntime at L94, and that variant of rollbackRuntime was deprecated as part of WFCORE-102 as well. The core now automatically handles removing services that were added by a step during rollback of that step.
