The Extbase action controller does not worry about clearing
cache or changing plugins from USER to USER_INT as this is
now handled within Extbase Bootstrap, reducing
logic within Extbase controllers.

Future iterations in this area then allow to
a) have Extbase in BE not depend on an active cObject anymore
b) have Extbase Bootstrap be sending headers to
   its parent object.
