Image prune --filter is fully implemented in the api, http api yet not connected with the cli execution. User trying to use filters does not see the effect. This commit adds glue code to enable possiblity of using --filter in prune in the cli execution. Signed-off-by: Jakub Guzik <jakubmguzik@gmail.com>
