What changes were proposed in this pull request?
Introducing a new OM performance metric for capturing the latency of the
checkAccessmethod in theOmMetadataReaderclass. This metric shall be crucial in measuring the time it takes for the security providers that extend support for Ozone ACLs to verify the access permissions granted for a given Ozone object.This metric could potentially serve as a valuable tool in identifying any performance bottlenecks and improving efficiency.

How was this patch tested?
The patch has been tested over a cluster that has the Ozone services running to see what the metric looks like. A sample screenshot of the Prometheus UI has been attached (for reference) capturing
