hypershift_hostedclusters_failure_conditions metric incorrectly reports multiple clusters for a single cluster

The hypershift_hostedclusters_failure_conditions metric produced by the HyperShift operator does not report a value of 0 for conditions that no longer apply. The result is that if a hostedcluster had a failure condition at a given point, but that condition has gone away, the metric still reports a count for that condition.

always

1. Create a HostedCluster, watch the hypershift_hostedclusters_failure_conditions metric as failure conditions occur.
2.
3.

A cluster count of 1 with a failure condition is reported even if the failure condition no longer applies.

Once failure conditions no longer apply, 0 clusters with those conditions should be reported.

The metric should report an accurate count for each possible failure condition of all clusters at any given time.
