Update DNS Shotgun parameters for an updated dataset

Browse Source 
We've switched to an updated dataset for shotgun jobs. The change in
underlying traffic caused the more sensitive doh-get (and partially dot)
jobs to overload the resolver, making the jobs unstable and unreliable,
due to an increased number of timeouts.

Readjust the load parameters slightly to avoid exceeding ~2 % of
timeouts in the cold cache scenario to stabilize the job results.

(cherry picked from commit 338389b3eb)
