KUDU-3549 fix WriteAsPrometheus() for non-arithmetic gauges
This patch fixes WriteAsPrometheus() implementation for string-based
gauges. The original changelist that introduced Prometheus metrics
had a proper implementation of WriteAsPrometheus() only for StringGauge,
but any FunctionGauge for a non-arithmetic type (e.g., for std::string)
would still output a string value in Prometheus text format, and that
could not be consumed by Prometheus. The patch also contains a test
scenario that would fail without the fix.
This is a follow-up to 00efc6826ac9a1f5d10750296c7357790a041fec.
