ISPN-4693 Initial submission of handling for orphaned transactions.

Based off of production settings, I needed to iterate over both maps, since there are conditions where a local transaction can be orphaned as well.  

I'm wondering if instead of a rollback command, we directly grab the lock container and release the locks that way (and removing the transactions from the table via the existing methods).  I don't see how any exception can occur before the lock interceptors, but I'm not as familiar with the 7.0 code. 
I'd log stale transactions as a warning.
