In auto provisioning we push 300 seconds expiration time to give ability for a device

to register within 300 seconds. If the registration is performed within 300 seconds

(e.g. in 60 seconds), the proper work of the device is ensured.

We advise to configure 60 seconds registration time for DNS-SRV type of registration.

This is because we would like to have some control over the expiration time from our side.

Therefore in case we decide to decrease it in future - there will be no need for customers

to change the expiration time from 300 to 60 seconds.
