CloseChannel returns fee_per_vbyte in close_pending updates, but this is not shown in the output of lncli closechannel. The only thing we get is

Channel close successfully initiated
Channel close transaction broadcasted: 474a2e1f4b6157024c69f01b802efc4d325f9577f543832b2bf92fef636d0cb1

}

I'd like to see this included in the output of lncli closechannel so that we can have some reassurance that the --sat_per_vbyte is working right and so that when the --conf_target option is used, we know what fee rate that it automatically chose. This is particularly useful when using RBF cooperative close so that we know the old fee was in fact replaced.
