Fix/staking migrations (#300)

### Description
This PR applies missing staking migrations with some changes in v9 and
v11:
1. The migration to v9 has been altered to set the next pallet version
only. The remaining parts are not needed because we are already using
VoterList and it's in good condition. To change the migration, the
source code has been moved from workplace dependencies to the Cere repo.
2. In migration to v11, there is no need to move data from BagsList to
VoterList since we are already using VoterList. Instead, BagsList should
be removed.
  3. Benchmarking and Clippy checks are disabled for the sake of time.
  4. Apply migrations to v8, v10, v12, v13.
  
 Notes:
1. BagsList has been migrated to VoterList in
[v4.1.0](https://github.com/Cerebellum-Network/blockchain-node/compare/v4.0.0..v4.1.0#diff-8979c26ba42edc867488ec32089e6e48df0774444fe9a4726a09d129545060dbR1347)
but the migration was not written and executed properly.
2. Staking pallet changes can be reviewed with `diff -r
substrate/frame/staking blockchain-node/pallets/staking` or with
[kdiff3](https://kdiff3.sourceforge.net/) if one prefers graphical UI.
In both cases, you must have
[Substrate](https://github.com/paritytech/substrate) locally.
3. To get back to the original staking pallet,
[b80f635](b80f635),
[5c8fcbd](5c8fcbd),
and
[1b71aa8](1b71aa8)
should be reverted
