[mongo] gracefully fail on operation samples colleciton when node is in recovering mode

[lu-zhengda]

What does this PR do?

Fixes a bug that caused the MongoDB DBM operation samples collection to crash when a node is in recovering mode.

Motivation

Previously, the DBM operation samples collection could crash with a NotPrimaryError if a node entered recovering mode. This situation often occurs when a MongoDB node is disconnected from the replica set for an extended period and is catching up on replication after rejoining the set. This PR ensures the integration can gracefully handle nodes in recovery, preventing unexpected crashes.
