Description

Pack provides two compensation modes 'forward' and 'reverse'. Users can choose which mode to use by configuring the retries property of @Compensable annotation

If retries == 0 then reverse otherwise forward, more detail [1].

This looks confusing, we need to define a clear attribute that represents the mode of compensation

I suggest adding a 'mode' attribute to the @Compensable annotation, which contains three options:

• forward 
• reverse (default)
• combine (first forward then reverse)
