Controlling pool size

Some geocoders are using a pooling mechanism for optimal performance. Using this setting through the CLI gives you more control as you test and identify the optimal pool size for your environment.

# Country level settings (use iso3 country code for country level settings)

# this will set the max pool size, default: 5
setting --n POOL_MAX_ACTIVE --v "8" --d "/path/to/config/dir" --t USA
