• Use non-capturing group for subdomain matching in ActionDispatch::HostAuthorization

  Since we do nothing with the captured subdomain group, we can use a non-capturing group instead.

• Fix ActionController::Live to copy the IsolatedExecutionState in the ephemeral thread.

  Since its inception ActionController::Live has been copying thread local variables to keep things such as CurrentAttributes set from middlewares working in the controller action.

  With the introduction of IsolatedExecutionState in 7.0, some of that global state was lost in ActionController::Live controllers.

• Fix setting trailing_slash: true in route definition.

  get '/test' => "test#index", as: :test, trailing_slash: true
  
  test_path() # => "/test/"

• Make Session#merge! stringify keys.

  Previously Session#update would, but merge! wouldn't.
