Fixes https://github.com/paritytech/polkadot-sdk/issues/106 Port of cumulus PR https://github.com/paritytech/cumulus/pull/2960 This PR adds the ability to bid for collator slots even after the max number of collators have already registered. This eliminates the first come, first served mechanism that was in place before. Key changes: - added `update_bond` extrinsic to allow registered candidates to adjust their bonds in order to dynamically control their bids - added `take_candidate_slot` extrinsic to try to replace an already existing candidate by bidding more than them - candidates are now kept in a sorted list in the pallet storage, where the top `DesiredCandidates` out of `MaxCandidates` candidates in the list will be selected by the session pallet as collators - if the candidacy bond is increased through a `set_candidacy_bond` call, candidates which don't meet the new bond requirements are kicked # Checklist - [ ] My PR includes a detailed description as outlined in the "Description" section above - [ ] My PR follows the [labeling requirements](https://github.com/paritytech/polkadot-sdk/blob/master/docs/CONTRIBUTING.md#process) of this project (at minimum one label for `T` required) - [ ] I have made corresponding changes to the documentation (if applicable) - [ ] I have added tests that prove my fix is effective or that my feature works (if applicable) - [ ] If this PR alters any external APIs or interfaces used by Polkadot, the corresponding Polkadot PR is ready as well as the corresponding Cumulus PR (optional) --------- Signed-off-by: georgepisaltu <george.pisaltu@parity.io>
