They were deprecated in Newton. This patch cleans them up.
Note: it does not mean that the features will not work anymore. On the
contrary, now API will consistently sort and paginate for plugins that
honour the relevant sorting/pagination parameters.
Note2: base resource controller still allows to pass
allow_pagination=False and allow_sorting=False parameters to disable the
features if a registered plugin does not support the features yet.
