[danielealbano]

This PR introduces 4 groups of changes:

• RMW (Read-Modify-Write) operations in the multi producer mutli consumer hashtable with the ability to commit an update, commit a delete or abort the operation
• RMW operations in the storage db, with the ability to commit an update, commit a delete or abort the operation, which will actual become a commit delete if the key being accessed is expired and no new values are supplied and the delete is not requested
• The SET command now properly supports the NX, XX, GET and KEEPTTL options
• The integration tests for the currently supported Redis commands have been improved drammatically making them much more simple and understandable and a new set of tests have been introduced for the SET command
