final class JsonTunableMapper extends AnyRef

Parses a given JSON string into a TunableMap. The expected format is:

"tunables":
  [
     {
       "id" : "$id1",
       "value" : $value,
       "type" : "$class"
     },
     {
       "id" : "$id2",
       "value" : $value,
       "type" : "$class",
       "comment": "optional comment"
     }
 ]

Where $id1 and $id2 are unique identifiers used to access the Tunable, $value is the value, and $class is the fully-qualified class name (e.g. com.twitter.util.Duration)

If the JSON is invalid, or contains duplicate ids for Tunables, parse will return a Throw. Otherwise, parse returns Return[TunableMap
