Smart contracts for ethereum-storage package

RequestHashStorage allows to declare a hash NewHash(hash, submitter, feesParameters). Only a whitelisted contract can declare hashes.
RequestOpenHashSubmitter entry point to add hashes in RequestHashStorage. It gives the rules to get the right to submit hashes and collect the fees. This contract must be whitelisted in RequestHashStorage. The only condition for adding hash is to pay the fees.
StorageFeeCollector parent contract (not deployed) of RequestOpenHashSubmitter, computes the fees and send them to the burner.
