api/system/encrypt or decrypt REST API will not propagate other nodes's db.properties files.
**Note this propagative issue is only for db.properties file, other password's encryption/decryption in config descriptor is working as expected.
Steps to reproduce
1. Run api/system/encrypt or decrypt REST API to primary node, we can see password encrypted or decrypted of db.properties file in primary node.
2. But, we can not see any changes of db.properties files in secondary node
**vice versa is same result - run encrypt/decrypt API at secondary, but, nothing changed in primary node's db.properties
As a workaround, for encrypting db.properties file, we need to run api/system/encrypt to each nodes individually.
