Brief description

This PR adds transaction supports for Box module and apply the changes for some classes using transaction methods.
Issue: #742

Change list

• Drop openedSession: prevents problems. Basically, a function creates a session then it owns the transaction lifecycle.
• Add try/catch/finally: catches errors when working with MongoDB and return them easily.
• Apply changes to the use of transaction methods in classes (Box module)
• Add TransactionCommitError.ts, Transaction.ts.
• ESLint

So I think the transaction helper methods can be simplified a little bit. I added more specific comments about them. Then the bigger idea behind this whole transaction support change was to implement a better Transaction ownership principle. Meaning that the method that starts / initializes the transaction must be the one that cancels or commits it. So the helper methods that take in the session shouldn't call the cancelTransaction. They only take the session as param so that the session can be passed to the BasicService so that the db operations are all under the same transaction. But the parent method is responsible for that transaction lifecycle.

And maybe consider matching naming for the transaction helpers. So initialize-, abort-, commitTransaction or Session. A bit nitpicky but might be easier to follow if all helpers are called somethingSession or somethingTransaction.

Well done. Good work
