i'm doing some WIP for Atlantis and haven't merged in the actual atlantis.yaml into our main branch yet, but I have the webhook on github working and Atlantis itself setup.... Meanwhile I have some TF code that I that I opned up a PR on a seperate branch... it would appear that Atlantis tries to process and attempt to run anyway with default settings.... is there a way to tell Atlantis to no op if an atlantis.yaml file is missing?
