Support float queryValue for MongoDB scaler

[xiaok80s]

Proposal

Currently, the MongoDB scaler requires queryValue to be an integer. This feature request proposes adding support for floating-point values to allow more flexible query conditions.

Use-Case

I have a ScaledObject with minReplicaCount set to 1 and maxReplicaCount set to 10. My goal is to always maintain one idle pod whenever possible. Since idleReplicasCount doesn’t work in this case, I tried setting queryValue to 0.9 to keep the replica count one above the required amount. However, I found that queryValue does not support float values. I tested this with MSSQL and MySQL, and both allow float values for queryValue or targetValue.

Is this a feature you are interested in implementing yourself?
