Test 1000 users in 1000 MUC with Prosody + Converse
@MattJ Will provide a test server with 1000 users in 1000 MUC.
@dele Will plug a Converse.js on it, configured as our sib-chat https://git.happy-dev.fr/startinblox/components/sib-chat/blob/master/sib-chat.js#L194
This test will not include sib-core. You may want to try it on our side after.
With this test, we're trying to see if we can get ride of the singleton
parameter with our use case.
