*
* Define as 1 to enable attach backoff feature
*
* When this feature is enabled, an exponentially increasing backoff wait time is added between attach attempts.
* If device is sleepy, the radio will be put to sleep during the wait time. This ensures that a battery-powered sleepy
* end-device does not drain its battery by continuously searching for a parent to attach to (when there is no
* router/parent for it to attach).
*
* The backoff time starts from a minimum interval specified by
* `OPENTHREAD_CONFIG_MLE_ATTACH_BACKOFF_MINIMUM_INTERVAL`, and every attach attempt the wait time is doubled up to
* `OPENTHREAD_CONFIG_MLE_ATTACH_BACKOFF_MAXIMUM_INTERVAL` which specifies the maximum wait time.
*
* Once the wait time reaches the maximum, a random jitter interval is added to it. The maximum value for jitter is
* specified by `OPENTHREAD_CONFIG_MLE_ATTACH_BACKOFF_JITTER_INTERVAL`. The random jitter is selected uniformly within
* range `[-JITTER, +JITTER]`. It is only added when the backoff wait interval is at maximum value.
