Let's get a parsercache host in eqiad to serve traffic.
Probably the easiest would be to migrate pc1014 (spare) and let it serve traffic instead of pc1011. If we need to roll back we can promote pc1011 back to pc1 master.

pc1014 is now serving as pc1 master with 10.6.8.
pc1011 has been reconfigured as a slave of pc1014 so the keys aren't lost and once it needs to go back as master it will have the same content.
