Increase default X31 val from 5 to 15 seconds

It was spotted that in some deploys with satellite links and heavy load,
the roundtrip times for CR and CC can go slightly over 12 seconds, so
better increase the default value to 15 seconds to be on a safer place
and avoid operation problems with default configuration.
