MarshalJSON creates JSON formatted the same way as jsonpb so that the
OpenCensus service can correctly determine the underlying value type.
This custom MarshalJSON exists because,
by default BucketOptionsExplicit is JSON marshalled as:
{"bounds":[1,2,3]}
but it should be marshalled as:
{"explicit":{"bounds":[1,2,3]}}
