[27/41] chttpd commit: updated refs/heads/2080-port-cors to e2c2bd7

[ch...@apache.org]

Remove _config route on cluster

In order to avoid users shooting themselves in the foot by using
`/_config/` on a clustered CouchDB with a loadbalancer in front,
we remove it on `15984` - it will be available for single-node-
mode on the backdoor port (`15986`) or for users that are feeling
lucky which want to fire curl requests to every node.

It also allows Fauxton to detect if it is running on a the backdoor
port. Fauxton will - if it gets a 200 instead of a 404 - show the
config-section to the user.
