The loading preference is:
1. CLI flag
2. `PRIVATE_KEY`
3. `PRIVATE_KEY_PATH`
4. Find a `.pem` file in the current working dir
Changes:
- break out PK loading logic into module `lib/private-key.js`
- add more info to error messaging if probot fails to find a PK
- add tests
- add note to deployment docs
