Can we remove or quiet down the commit bot in the chatrooms

[Nate Graham]

I find it rather difficult to use #plasma for chats and discussions 
because of the near-constant spam from the commit announcement bot.

It's not that it's useless to have commits announced, but when it 
happens in a room where humans are interacting, it's rather disruptive 
and spammy. Maybe we could move the bot into a dedicated commit announce 
room so that the people who care about this can still see the 
announcements there?

Alternatively could we change the bot so that it sends one message for 
each commit instead of like 4 or 5?
