* test_encrypt_files_many_keys_multiple_keys passing
- buffer chunk size unified between single key and multiple key path,
which shouldn't be necessary but can fix later.
* test_encrypt_file_many_keys_bad_key_length passing
* Also implement more storage contract logic
* Add transactions for proof validation,
* Move storage state members into system storage account userdata
* Remove logging init from storage program: saw a crash in a test
indicating the logger being init'ed twice.
* Add entry_height mining proof to indicate which segment the result is
for
* Add an interface to get storage miner pubkeys for a given entry_height
* Add an interface to get the current storage mining entry_height
* Set the tvu socket to 0.0.0.0:0 in replicator to stop getting entries
after the desired ledger segment is downloaded.
* Use signature of PoH height to determine which block to download for
replicator.
* Use IV to make unique identies
* Use hex! macro for hex literal and not string converted to u8 slice
* fix sha sampling to control init/end of sha state
* Move ledger write to its own stage
- Also, rename write_stage to leader_vote_stage, as write functionality
is moved to a different stage
* Address review comments
* Fix leader rotation test failure
* address review comments
