[FEA] Random return code choice out of CSV specified in substituteReturnCode

[gerashegalov]

Is your feature request related to a problem? Please describe.
I wish the Fault Injection Tool allowed comma-separated values for substitute Return Code such that I don't need a verbose list of separate rules for each one individually

Describe the solution you'd like

       "cuLaunchKernel_ptsz": {
           "percent": 1,
           "injectionType": 2,
           "substituteReturnCode": "2,3,999" ,
           "interceptionCount": 1000
       }

with the semantic: if the rule is matched pick one of the values randomly

Describe alternatives you've considered
replicate the rule per return code
