	Provider     addr.Address

	// Label is an arbitrary client chosen label to apply to the deal
	Label DealLabel

	// Nominal start epoch. Deal payment is linear between StartEpoch and EndEpoch,
	// with total amount StoragePricePerEpoch * (EndEpoch - StartEpoch).

In the current iteration, it will be released when the sector containing the storage deals expires, even though some storage deals can expire earlier than the sector does. Collaterals are denominated in PerEpoch to incur a cost for self dealing or minimal deals that last for a long time. Note: ClientCollateralPerEpoch may not be needed and removed pending future confirmation. There will be a Minimum value for both client and provider deal collateral.
