Improve logging and error handling

[sean-krail]

This ticket will track a running list to improve logging and error handling.

• Improve logging across the whole action's lifecycle - setup, filtering, polling, and conclusion.

• Let user know when the repository doesn't exist, the repository's ref doesn't exist, or the token doesn't have access to the repository. Right now the action throws this exception:

  (node:2762) UnhandledPromiseRejectionWarning: HttpError: Not Found

  (node:2762) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)
  (node:2762) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
