Timeout value for object change inidication packets shall be increased from 3 to 10 seconds

After sending an object change indication to the application, the stack expects that the response paket is received within 3 seconds. If it does not receive this packet within 3 seconds, it rejects the original SET-ATTRIBUTE service with status code 0x1E (Embedded service failed).

In case the host application stores remanent data, it might take more than 3 seconds to actually process the indication.

Therefore, this value shall be increased to 10 seconds.
