This is the 2nd installment for the AccountsDb replication.
Summary of Changes
The basic google protocol buffer protocol for replicating updated slots and accounts. tonic/tokio is used for transporting the messages.
The basic framework of the client and server for replicating slots and accounts -- the persisting of accounts in the replica-side will be done at the next PR -- right now -- the accounts are streamed to the replica-node and dumped. Replication for information about Bank is also not done in this PR -- to be addressed in the next PR to limit the change size.
Functionality used by both the client and server side are encapsulated in the replica-lib crate.
There is no impact to the existing validator by default.
Tests:
Observe the confirmed slots replicated to the replica-node.
Observe the accounts for the confirmed slot are received at the replica-node side.
Account data hashing used to use different ways of hashing on different
clusters. That is no longer the case, but the old code still existed.
This commit removes that old, now used code.
**NOTE** The golden hash values in bank.rs needed to be updated. Since
the original code that selected the hash algorithm used `if >` instead
of `if >=`, this meant that the genesis block's hash _always_ used the
old hashing method, which is no longer valid.
Validated by running `cargo test` successfully.
