Increase pool size to 15 permanent connections

Browse Source 
At the same time, decrease the number of workers from 5 to 4.

Effect on max db connections will be the same - although with a higher
"resting" number of connections.

Before:
12 (instances) * 5 (workers) * 20 (10 permanent + 10 overflow) = 1200

After:
12 (instances) * 4 (workers) * 25 (15 permanent + 10 overflow) = 1200
