Encourage clients to use secp256k1 wallet for deal making

[jennijuju]

The lotus team accidentally discovered that some clients are using bls (f3) wallet account to make deals. And using bafy2bzaceblq7zpmavxtnahcmstnip5vrokw2w6hadmqewd3x47n23hgxbyce as an example, it makes ~35% gas used for this PSD message is actually used for verifying client signature. However, if the client used a sect256k1 address, it can be 10x cheaper (see gas price list here) and will save SP a lot of gas cost in PSD messages -> potentially leads to lower ask price for deal onboarding in general in the longer term. (also saves chan bandwidth a bit)

Therefore, for future datacap allocations, we'd like to propose to notary to encourage verified client to use secp256k1 address or consider even only allocate DataCap to secp256k1 address.

to be clear.. this is an immediate action that can be taken for filecoin-project/FIPs#211 but def not the long term solution
