Websockets mean we make more connections to apache. Bump the connection limits to 4096 connections total as this appears to handle summit load. Change-Id: I87b6d06b5b730bde48d60fcbd6c025de5581b672

# Etherpad Lite clients create a lot of connections. To be able to support
|
|
# Several hundred concurrent users we need to make sure that we allow a few
|
|
# thousand concurrent connections. This should be ok as typical etherpad use
|
|
# involves a couple writers then a bunch of lurkers. The cost of lurkers
|
|
# is basically the TCP connection as they don't create DB writes and so on.
|
|
# In addition to allowing for connection growth, keep a healthy number of
|
|
# spare threads around to better handle thundering herds of users (eg at the
|
|
# start of summit sessions).
