mmlid: Move StorageAccessApiInfo config param inside DealMaking section

[dirkmc]

On the mm-retrieve branch there is a new config param called StorageAccessApiInfo. The param is at the top level of config. It stores a list of RPC APIs of each miner that boost can read data from. This allows a boost instance that stores data to miner A to also serve data from miner B (because LID stores the indexing information for both miner A and miner B).

In practice the StorageAccessApiInfo parameter is only relevant for graphsync retrievals (booster-http and booster-bitswap have their own mechanisms for specifying the list of miners to serve data from). It would be more appropriate to put it inside the DealMaking section of config where the other retrieval config params are.
