Closes#416
As I mentioned in the above issue `balance_to_points` conversion
currently overflows the `Balance` types even before computing the actual
points for the given tokens. This fixes that,
Addresses #409.
This request has been raised by multiple community members - the ability
for the nomination pool root role to configure permissionless commission
claiming:
> Would it be possible to have a claim_commission_other extrinsic for
claiming commission of nomination pools permissionless?
This PR does not quite introduce this additional call, but amends
`do_claim_commission` to check a new `claim_permission` field in the
`Commission` struct, configured by an enum:
```
enum CommissionClaimPermission {
Permissionless,
Account(AccountId),
}
```
This can be optionally set in a bonded pool's
`commission.claim_permission` field:
```
struct BondedPool {
commission: {
<snip>
claim_permission: Option<CommissionClaimPermission<T::AccountId>>,
},
<snip>
}
```
This is a new field and requires a migration to add it to existing
pools. This will be `None` on pool creation, falling back to the `root`
role having sole access to claim commission if it is not set; this is
the behaviour as it is today. Once set, the field _can_ be set to `None`
again.
#### Changes
- [x] Add `commision.claim_permission` field.
- [x] Add `can_claim_commission` and amend `do_claim_commission`.
- [x] Add `set_commission_claim_permission` call.
- [x] Test to cover new configs and call.
- [x] Add and amend benchmarks.
- [x] Generate new weights + slot into call
`set_commission_claim_permission`.
- [x] Add migration to introduce `commission.claim_permission`, bump
storage version.
- [x] Update Westend weights.
- [x] Migration working.

What does this PR do?
- Introduced the TotalValueLocked storage for nomination-pools.
- introduced a slashing api in mock.rs
- additional test for tracking a slashing event towards a pool without
sub-pools
- migration for the nomination-pools (V6 to V7) with
`VersionedMigration`
Why are these changes needed?
this is the continuation of the work by @kianenigma in this
[PR](https://github.com/paritytech/substrate/pull/13319)
How were these changes implemented and what do they affect?
- It's an extra StorageValue that's modified whenever funds flow in or
out of staking for any of the `bonded_account` of `BondedPools`
- The `PoolSlashed`event is now emitted even when no `SubPools` are
found
Closes https://github.com/paritytech/polkadot-sdk/issues/155

closes https://github.com/paritytech/polkadot-sdk/issues/158.
partially addresses
https://github.com/paritytech/polkadot-sdk/issues/226.
Instead of fragile calculation of current balance by looking at `free
balance - ED`, Nomination Pool now freezes ED in the pool reward account
to restrict an account from going below minimum balance. This also has a
nice side effect that if ED changes, we know how much is the imbalance
in ED frozen in the pool and the current required ED. A pool operator
can diligently top up the pool with the deficit in ED or vice versa,
withdraw the excess they transferred to the pool.
## Notable changes
- New call `adjust_pool_deposit`: Allows to top up the deficit or
withdraw the excess deposited funds to the pool.
- Uses Fungible trait (instead of Currency trait). Since NP was not
doing any locking/reserving previously, no migration is needed for this.
- One time migration of freezing ED from each of the existing pools (not
very PoV friendly but fine for relay chain).
Closes https://github.com/paritytech/polkadot-sdk/issues/158
In our last FRAME call it was discussed that a likely solution to the ED
imbalances is lazily fixing the pools as they are interacted with.
So, we should add some tiny tolerance to the try-state checks so next
time there's an ED change they don't start failing until they've all
been interacted with.
### Update 12 Sept
Rather than adding tolerance, have replaced the `ensure` with a warning.

* frame: Default for GenesisConfig in no_std
`Default` for `GenesisConfig` will be required for no_std in no native
runtime world. It must be possible to instantiate default GenesisConfig
for pallets and runtime.
* ".git/.scripts/commands/fmt/fmt.sh"
* hash69 in no_std reverted
* derive(DefaultNoBound) for GenesisConfig used when possible
* treasury: derive(Default)
* Cargo.lock update
* genesis_config: compiler error improved
When std feature is not enabled for pallet, the GenesisConfig will be
defined, but serde::{Serialize,Deserialize} traits will not be
implemented.
The compiler error indicates the reason of latter errors.
This is temporary and serde traits will be enabled with together with
`serde` support in frame.
