Manual testing show it works!

[settings]
enable_tracing = false

[relaychain]
default_command = "polkadot"
chain = "rococo-local"

[[relaychain.nodes]]
name = "alice"
validator = true

[[relaychain.nodes]]
name = "bob"
validator = true

[[parachains]]
id = 2000
addToGenesis = true

  [parachains.collator]
  name = "collator01"
  command = "adder-collator"
  args = ["-lparachain=debug"]

[[parachains]]
id = 2001
addToGenesis = true

  [parachains.collator]
  name = "collator02"
  command = "adder-collator"
  args = ["-lparachain=debug"]

[[parachains]]
id = 2002
addToGenesis = true

  [parachains.collator]
  name = "collator03"
  command = "adder-collator"
  args = ["-lparachain=debug"]

[types.Header]
number = "u64"
parent_hash = "Hash"
post_state = "Hash"

zombi --provider native spawn cumulus/zombienet/zombienet-sdk/tests/test-para-ids.toml

and then I went to runtime calls in https://polkadot.js.org/apps/?rpc=ws://127.0.0.1:59016#/runtime

and it shows:

So, success!

Implementation of #9053 --------- Co-authored-by: alindima <alin@parity.io>

@tdimitrov

Implements the `CollationManager` and the new collator protocol (validator side) subsystem. Issues #8182 and #7752. These are the big remaining parts which would enable us to test the entire implementation. TODO: - [ ] add a couple more unit tests (see the suggestions at the bottom of the tests file) - [x] polish the ClaimQueueState and verify if it's sufficiently covered by unit tests - #10334 - #10368 - [x] add metrics and polish logs - #10730 - [x] add a CLI parameter for enabling the experimental subsystem (and remove the compile-time feature) -> #10285 - [x] implement registered paras update, using #9055 - [ ] do some manual zombienet tests with v1 protocol version and with restarting validators (including syncing with warp sync) - [x] prdoc - [x] Rollback - 03e8915 - 05e1497 These commits were added just to run the CI tests for this PR with the new experimental protocol After merging: - [ ] versi testing Uses a slightly modified version of the ClaimQueueState written by @tdimitrov in #7114. --------- Co-authored-by: Tsvetomir Dimitrov <tsvetomir@parity.io> Co-authored-by: Serban Iorga <serban@parity.io> Co-authored-by: Serban Iorga <serban300@gmail.com> Co-authored-by: cmd[bot] <41898282+github-actions[bot]@users.noreply.github.com>
