By default this will be enable.
Motivation
The #3212 import a feature: convert bookie to read-only mode when any ledger disks is full.
In our practice, we found that when the bookie disk is full, if it is not changed to Read Only mode, a large number of messages will fail to be written to the ledger disk. And because the bookie status is still available at this time, no alarm is given to the maintenance personnel, resulting in slow access for the maintenance personnel.
That feature has been in place for some time. It is safe to enable it default.
