changelog/10.7.0_2021-03-26/37272
Change: Use OcsController and routes instead of API::register
Implemented OcsController and removed a separate file to register ocs routes.
Also some deprecated and legacy OC_OCS classes removed. OcsController now
checks CSRF token instead of OCS_API_REQUEST header.
