* fix erasure, more tests for full blobs, more metrics
* Revert "Revert "Use Rust erasure library and turn on erasure (#3768)" (#3827)"
This reverts commit 4b8cb7297734c8ce94d7fc073704c01ec45eb4b7.
* split out erasure into new crate; add implementation using rust reed-solomon-library
* Track erasures with a &[bool] instead of indexes
* fix bug that reported the number of erasures incorrectly
* Introduce erasure `Session` for consistent config
* Increase test coverage; fix bugs
* Add ability to remove blobs from erasure meta tracking. test added
* Track deletion of coding blobs in blocktree via ErasureMeta. Added to
test
* Remove unused functions in blocktree
* add randomness to recovery thread to exercise recovery due to either new
data or coding blobs
* Add unit test for ErasureMeta index handling
* Re-enable test in broadcast stage
* Restart node test (#3459)
* Add test to local_cluster for restarting a node
* fix so that we don't hit end of epoch - leader not found before trying to transfer
* Do not look for confirmations, b/c nobody is voting on empty transmissions in this single node test
* move core tests to core
* remove window
* fix up flaky tests
* test_entryfication needs a singly-threaded banking_stage
* move core benches to core
* remove unnecessary dependencies
* remove core as a member for now, test it like runtime
* stop running tests twice
* remove duplicate runs of tests in perf
* locktower components and tests
* integrate locktower into replay stage
* track locktower duration
* make sure threshold is checked after simulating the vote
* check vote lockouts using the VoteState program
* duplicate vote test
* epoch stakes
* disable impossible to verify tests
* Mostly implement key-value store and add integration points
Essential key-value store functionality is implemented, needs more work to be integrated, tested, and activated.
Behind the `kvstore` feature.
