The listCollections command returns a readOnly field per collection that is true in case the collection data is read-only.
Right now, we are setting its value to true only when the queryableBackupMode and recoverFromOplogAsStandalone server parameters are set.

This ticket aims to investigate if there are other cases where we should set that field to true.
For example, I would expect it to be true when the setUserWriteBlockMode command has been called.
