Log test results one json object per test

[krisis]

Based on the following spec,

{
  "name":"mc",                                                     // SDK Name
  "function":"makeBucket(String bucketName)",                      // API name
  "args":"",                                                       // key value map, varName:value. Only arguements that devs may be interested in
  "duration":"15",                                                 // duration of the whole test in milli seconds
  "status":"PASS",                                                 // can be PASS, FAIL, NA
  "alert":"Information like whether this is a Blocker/ Gateway, Server etc can go here",
  "message":" descriptive error message"                           // error related, human readable  message. Should be taken care of if present
  "error":"stack-trace/exception message(only in case of failure)" // actual low level exception/error thrown by the program
}

Fixes #112

ms can be removed from the duration section, unit is implicit.
