feat(api): Validate Auth Tokens client-side (#1885)

Perform client-side validation of all Auth Tokens input to the Sentry CLI. To ensure future-compatibility, we only provide soft validation, meaning that we only print a warning message if we detect that the Auth Token is invalid – the CLI will still proceed with normal execution if the Auth Token is invalid.

Fixes GH-1859
