REFACTOR: Speed up by-ip lookups by introducing a new map entry (#2488)

Thankfully, the existing AllServers map is not exported, so we can
ensure that all the changes are only local to this file.

This also fixes a bug if renameServer was called with the same
name. (Probably calling code checked that case already.)
