Scale up Ireland to 6 Cloud Controller instances
Scale up Ireland to 6 Cloud Controller instances

A tenant reported some erratic API errors in Ireland. After some
digging we suspect Cloud Controller can get a bit overloaded. This
commit scales Ireland up from 4 to 6 Cloud Controller instances to
better meet demand.

At present our `api` VMs use EC2 `m5.large` instances. An on-demand
`m5.large` in Ireland (`eu-west-1`) costs ~$77/month. If reserved this
goes down to ~$54/month. Therefore these 2 extra instances will cost
$108–$154 depending upon how many are already reserved.

London has 12 `api` instances, whereas this PR only takes London up to
6. Money doesn't grow on trees and we haven't seen big enough problems
to scale Ireland up all the way yet.
