4LW MNTR command outputs in float when prometheus activated

We use zookeeper 3.6.1 in combination with solr 8.6.0 on our kubernetes cluster. For monitoring purposes we activated the prometheus metrics for zookeeper, which had the unexpected side effect that the 4lw mntr command now also outputs floats instead of the usual integers. This broke the parser on the solr side (SOLR-14752), because it was expecting ints.

This ticket is to discuss if this is actually a bug or expected behavior because this change isn't mentioned anywhere in the release notes or documentation.
