After `putsvc.Service` started to support additional container broadcast
of the saved objects there is no more need to perform broadcast of
tombstone object in `deletesvc.Service`.
Make `putsvc.Service` to perform additional broadcast of `TOMBSTONE`
objects. Remove `broadcastTombstone` stage from `deletesvc.execCtx`,
from now it is encapsulated in `saveTombstone` stage. Remove no longer
needed `putsvc.PutInitPrm.WithTraverseOption` method.
