                stack, there is no key of "mesh/role" in nvs. In the new version
                mesh stack, key of "mesh/role" is added in nvs, recovering node
                information needs to check "mesh/role" key in nvs and implements
                selective recovery of mesh node information. Therefore, there may
                be failure in recovering node information during node restarting
                after OTA.

                The new version mesh stack adds the option of "mesh/role" because
                we have added the support of storing Provisioner information, while
                the old version only supports storing node information.

                If users are updating their nodes from old version to new version,
                we recommend enabling this option, so that system could set the flag
                in advance before recovering node information and make sure the node
                information recovering could work as expected.

            additional upper limit of 144 hours).

            In order to fulfill the above requirement, even if the node might
            be powered off once in a while, we need to store persistently
            how many hours the node has been in the state. This doesn't
            necessarily need to happen every hour (thanks to the flexible
            duration range). The exact cadence will depend a lot on the
            ways that the node will be used and what kind of power source it
            has.

            Since there is no single optimal answer, this configuration
            option allows specifying a divider, i.e. how many intervals
            the 96 hour minimum gets split into. After each interval the
            duration that the node has been in the current state gets

            This value affects memory and call stack consumption, which
            is why the default is lower than the maximum that the
