parse-server's file creation and deletion bypasses `readOnlyMasterKey` write restriction

Impact The readOnlyMasterKey can be used to create and delete files via the Files API POST /files/:filename, DELETE /files/:filename. This bypasses the read-only restriction which violates the access scope of the readOnlyMasterKey. Any Parse Server deployment that uses readOnlyMasterKey and expos...
