Request: Make exceptions subclass from a single parent class

[Roguelazer]

Right now, if you want to handle exceptions, your choices are to thread through a block to every single function call, or to do weird import gymnastics to get at the hidden codegen modules.

If the various ApiError types all subclassed from a single public exception (something like Hubspot::BaseException), it'd be much more straightforward to use normal Ruby exception handling.

What I'm doing for now is basically

begin
  # do lots of hubspot stuff
rescue => exc
  raise exc unless exc.class.name.match?(/\AHubspot::.*ApiError\z/)
  # handle hubspot exceptions
end

Hey @Roguelazer. Sounds good, we'll discuss it with the team and explore what we can do with it.
