**_PR migrated from https://github.com/paritytech/polkadot/pull/6782_**
This PR will upgrade the network protocol to version 3 -> VStaging which
will later be renamed to V3. This version introduces a new kind of
assignment certificate that will be used for tranche0 assignments.
Instead of issuing/importing one tranche0 assignment per candidate,
there will be just one certificate per relay chain block per validator.
However, we will not be sending out the new assignment certificates,
yet. So everything should work exactly as before. Once the majority of
the validators have been upgraded to the new protocol version we will
enable the new certificates (starting at a specific relay chain block)
with a new client update.
There are still a few things that need to be done:
- [x] Use bitfield instead of Vec<CandidateIndex>:
https://github.com/paritytech/polkadot/pull/6802
- [x] Fix existing approval-distribution and approval-voting tests
- [x] Fix bitfield-distribution and statement-distribution tests
- [x] Fix network bridge tests
- [x] Implement todos in the code
- [x] Add tests to cover new code
- [x] Update metrics
- [x] Remove the approval distribution aggression levels: TBD PR
- [x] Parachains DB migration
- [x] Test network protocol upgrade on Versi
- [x] Versi Load test
- [x] Add Zombienet test
- [x] Documentation updates
- [x] Fix for sending DistributeAssignment for each candidate claimed by
a v2 assignment (warning: Importing locally an already known assignment)
- [x] Fix AcceptedDuplicate
- [x] Fix DB migration so that we can still keep old data.
- [x] Final Versi burn in

* Revert approval-voting subsystem
* Approval voting revert encapsulated within 'ops' module
* use 'get_stored_blocks' to get lower block height
* Fix error message

* range end number is last block number plus 1
* Apply code review suggestions
* Use tristate enum for block range in backend overlay
* Add clarification comment
* Add comments to private struct
* remove v0 primitives from polkadot-primitives
* first pass: remove v0
* fix fallout in erasure-coding
* remove v1 primitives, consolidate to v2
* the great import update
* update runtime_api_impl_v1 to v2 as well
* guide: add `Version` request for runtime API
* add version query to runtime API
* reintroduce OldV1SessionInfo in a limited way
* node/approval-voting: Introduce Backend trait and Overlaybackend
This commit introduces a Backend trait and attempts to move away
from the Action model via an OverlayBackend as in the ChainSelection
subsystem.
* node/approval-voting: Add WriteOps for StoredBlockRange and BlocksAtHeight
* node/approval-voting: Add load_all_blocks to overlay
* node/approval-voting: Get all module tests to pass.
This commit modifies all tests to ensure tests are passing.
* node/approval-voting: Address oversights in the previous commit
This commit addresses some oversights in the prior commit.
1. Inner errors in backend.write were swallowed
2. One-off write functions removed to avoid useless abstraction
3. Touch-ups in general
* node/approval-voting: Move from TestDB to dyn KeyValueDB
This commit removes the TestDB from tests.rs and replaces it with
an in-memory kvdb.
* node/approval-voting: Address feedback
* node/approval-voting: Add license to ops.rs
* node/approval-voting: Address second-pass feedback
* Add TODO
* node/approval-voting: Bump spec_version
* node/approval-voting: Address final comments.
