extend parsing instructions to use json object instead of plain txt

[mfederowicz]

related with #424

now we can use instead of txt format:

x = atomic.AddUint64(&x, 1) // MATCH /direct assignment to atomic value/

json format:

x = atomic.AddUint64(&x, 1) // json:{"MATCH": "direct assignment to atomic value","Confidence": 1}

of course this is only draft because I dont know how it should looks like logic to use all Failure properties, so I asume that for example we want to check if Confidence property have value equal to that setted up in json object, and if value is not equal then throw/log error otherwise everything is ok

this draft dont remove old MATH txt format, but add json feature, so we can use old format for some time :)

@chavacava what do you think about?

Hi @mfederowicz, thanks for the feature. We will be able to test rules with more precision ;)
