Pull Request Overview

This PR removes a redundant README.md file from the MongoDB Search documentation for external MongoDB deployments without TLS. The file contained a comprehensive quick start guide with 15 detailed steps for deploying MongoDB Search with external MongoDB instances, but appears to be redundant with other documentation.

MCK 1.5.0 Release Notes

New Features

• Improve automation agent certificate rotation: the agent now restarts automatically when its certificate is renewed, ensuring smooth operation without manual intervention and allowing seamless certificate updates without requiring manual Pod restarts.

Bug Fixes

• MongoDBMultiCluster: fix resource stuck in Pending state if any clusterSpecList item has 0 members. After the fix, a value of 0 members is handled correctly, similarly to how it's done in the MongoDB resource.
• MultiClusterSharded: Blocked removing non-zero member cluster from MongoDB resource. This prevents from scaling down member cluster without current configuration available, which could lead to unexpected issues.
