Perform a trivial Canvas operation to verify if the OAuth Token is valid. This will typically be used when we want an integration to fail fast. Some integrations might not notice that the OAuth token is invalid until halfway into whatever it is that they do. This was initially the case for the Scantron integration.

Throws:

NoLtiSessionException - When there isn't a valid ltiExcpetion

IOException - when exception communicating with canvas
