Update PoolCounterSettings.php in operations/mediawiki-config to handle default search on remote datacenter
Closed, ResolvedPublic

Description

This needs to auto-magically update the pool counter limits when $wgDefaultSearchCluster !== $wmgDatacenter. This is because there is an additional 40ms round trip latency from eqiad to codfw. For full text searches this likely isn't an issue, but for shorter queries like namespace queries and prefix search we will likely need to increase the pool counter size.
