nfd-master: increase controller resync period to 10 min

Increase the NFD API controller resync period from 5 to 10 minutes. The
resync causes nfd-master to replay all NodeFeature and NodeFeatureRule
objects, being effectively a "big hammer reset all" button. This should
only be needed as an "insurance" to fix labels et al in case they have
been manually tampered (outside NFD) and against certain bugs in nfd
itself. NFD is not supposed to manage anything fast-changing so 10
minutes should be enough.

This change only affects behavior when the NodeFeature API has been
enabled (with -enable-nodefeature-api).
