bring 25 new mediawiki appserver in codfw into production, rack A3 (mw2377 - mw2401)
Closed, ResolvedPublic

Description

35 new servers were procured in T271156.

Then they are being racked and get an OS in T274171 which was possible after we made room for them in T277119 et al.

This brings them to "insetup" state. But from there they need to get appserver puppet roles, we need to decide which hardware gets which role
exactly, add regexes in site.pp matching that, add them to conftool-data, create mcrouter certificates and more.

This type of ticket is often a missing step in our existing workflows.
