Do not ask to store credentials upon loading #32
Description
Hi,
Recently, AzureRMR asks the user whether or not to store credentials in a local file upon first loading the package. This behaviour is annoying as it breaks automatic deployments (e.g. Shiny apps), especially when run in interactive / development mode. It is not good practice to ask the user for input upon loading a library. Is it possible to disable the question and (if at all necessary) provide the user information ("please call AzureRMR::save_credentials() to store credentials, ..." or something like it)?
