Bastian Köcher f3bf5c1acd xcm: Change TypeInfo::path to not include staging (#1948 )

The `xcm` crate was renamed to `staging-xcm` to be able to publish it to
crates.io as someone as squatted `xcm`. The problem with this rename is
that the `TypeInfo` includes the crate name which ultimately lands in
the metadata. The metadata is consumed by downstream users like
`polkadot-js` or people building on top of `polkadot-js`. These people
are using the entire `path` to find the type in the type registry. Thus,
their code would break as the type path would now be [`staging_xcm`,
`VersionedXcm`] instead of [`xcm`, `VersionedXcm`]. This pull request
fixes this by renaming the path segment `staging_xcm` to `xcm`.

This requires: https://github.com/paritytech/scale-info/pull/197

Scored Pool Module

The module maintains a scored membership pool. Each entity in the pool can be attributed a Score. From this pool a set Members is constructed. This set contains the MemberCount highest scoring entities. Unscored entities are never part of Members.

If an entity wants to be part of the pool a deposit is required. The deposit is returned when the entity withdraws or when it is removed by an entity with the appropriate authority.

Every Period blocks the set of Members is refreshed from the highest scoring members in the pool and, no matter if changes occurred, T::MembershipChanged::set_members_sorted is invoked. On first load T::MembershipInitialized::initialize_members is invoked with the initial Members set.

It is possible to withdraw candidacy/resign your membership at any time. If an entity is currently a member, this results in removal from the Pool and Members; the entity is immediately replaced by the next highest scoring candidate in the pool, if available.

Interface

Public Functions

submit_candidacy - Submit candidacy to become a member. Requires a deposit.
withdraw_candidacy - Withdraw candidacy. Deposit is returned.
score - Attribute a quantitative score to an entity.
kick - Remove an entity from the pool and members. Deposit is returned.
change_member_count - Changes the amount of candidates taken into Members.

Usage

use pallet_scored_pool::{self as scored_pool};

#[frame_support::pallet]
pub mod pallet {
    use super::*;
    use frame_support::pallet_prelude::*;
    use frame_system::pallet_prelude::*;

    #[pallet::pallet]
    pub struct Pallet<T>(_);

    #[pallet::config]
    pub trait Config: frame_system::Config + scored_pool::Config {}

    #[pallet::call]
    impl<T: Config> Pallet<T> {
        #[pallet::weight(0)]
        pub fn candidate(origin: OriginFor<T>) -> DispatchResult {
            let who = ensure_signed(origin)?;

            let _ = <scored_pool::Pallet<T>>::submit_candidacy(
                T::RuntimeOrigin::from(Some(who.clone()).into())
            );
            Ok(())
        }
    }
}
