Failed Subscription Retry Timer

Default: 300 seconds
Range: 0-9999 seconds

The "Failed Subscription Retry Timer" determines the time when the device starts with a new subscription attempt after the previous attempt failed.
Two cases must be respected:

1. The SUBSCRIPTION was rejected through a 4xx, 5xx, 6xx status code.
   The timer is fired and the device waits with a new subscription attempt until the time expired.
2. The SUBSCRIBE was not responded
   The device repeats the subscription in the following interval:
   2.1 - 0,5 s, 1 s, 2 s, 4 s, 4 s, 4 s, 4 s, 4 s, 4 s, 4 s
3. 2.2 - Afterwards it waits until the Failed Subscription Time elapsed (e.g. 300 seconds) and starts with the interval again.
