[BP 7.1.5] Fix case_clause issue in stats mapping

Description

There is an XDCR stat that when is requested causes stats_reader process to crash. If this problem continues, it can lead to the node to restart many processes. Refer to original CBSE for more info.

BP of https://couchbasecloud.atlassian.net/browse/MB-55446#icft=MB-55446

 

Issue

Resolution

When the REST API attempted to access unsupported stats, such as meta_latency_wt, "stats_reader" crashed on the ns_server side.

ns_server now returns a "not_found" status when the REST API is called with unsupported stats.
