When using Skara on an internal repository, it will still print informational messages to users like:

"To use the /backport command, you need to be in the OpenJDK census and your GitHub account needs to be linked with your OpenJDK username (how to associate your GitHub account with your OpenJDK username)." And where I get the instructions here: https://wiki.openjdk.org/display/skara#Skara-AssociatingyourGitHubaccountandyourOpenJDKusername"

These kinds of messages need some customization options so we can tailor them to the environment the bot is operating in.
