Allow do_orm_execute() events to both receive the complete state of bind_argments, load_options, update_delete_options as they do already, but also allow them to *change* all those things via new execution options. Options like autoflush, populate_existing etc. can now be updated within a do_orm_execute() hook and those changes will take effect all the way through. Took a few tries to get something that covers every case here, in particular horizontal sharding which is consuming those options as well as using context.invoke(), without excess complexity. The good news seems to be that a simple reorg and replacing the "reentrant" boolean with "is this before do_orm_execute is invoked" was all that was needed. As part of this we add a new "identity_token" option allowing this option to be controlled from do_orm_execute() as well as from the outside.
