monitor: Add a handler function for REQUEST_SET_RESOURCE_FLAG

For users of capi, some information such as process information
does not be provided. To distinguish users, we set the visibility
of each resource to PUBLIC or PRIVATE due to the user's context.

When an user sets the visibility of the resource to PUBLIC and
then sets the interest of the resource attribute which has PRIVATE
visibility, the pass daemon will reject it and return -EPERM error.
