// Base class used to provide common functionality needed when registering a
// new remote access host instance in the CRD backend. Subclasses should
// override the methods which handle the steps which differ however the flow
// is generally the same for all workflows.
//
// Overview of the steps in the registration flow once StartHost() is called:
// 1.) Check for an existing host instance
// 2.) <optional> Exchange authorization_code for an access token
// 3.) Register the new host instance in the CRD backend
// 4.) Exchange the service account authorization_code for a refresh token
// 5.) Remove the existing host from the CRD backend
// 6.) Stop the existing host (if one is running)
// 7.) Write the host configuration file to disk
// 8.) Start the host service using the new configuration file
