Declare a handler which writes a plain-text response with information about the

Tips: The important thing to point out here is that healthcheckHandler is implemented as a method
on our application struct. This is an effective and idiomatic way to make dependencies available
to our handlers without resorting to global variables or closures - any dependency that the
healthcheckHandler needs can simply be included as a field in the application struct when we
initialize it in main()
