Create Request Metering Terms and Conditions Flow
If a node wants to know what kind of metering terms and conditions are offered by a metering notary it can request a notary’s Metering T&Cs. The notary will respond by instigating a ‘Propose Metering T&C flow and sending its default metering T&Cs. Note: need to decide which party pays for the notarisation of this - I would suggest that the Node pays for this - but the metering notary gives it some credit so that the fee can be split, but at the same time preventing spam attacks.
