This proposal aims to change the configuration of three operations on: Fast-unstake pallet, Staking pallet, Nomination pools pallet, particularly:

1. Increasing the minimum number of tokens to create a nomination pool **from 200 DOT to 500 DOT**.

2. Increasing the bond size required to become a direct nominator from **100 DOT to 250 DOT**.

3. **Enabling fast unstake** on Polkadot: this has been well tested in Kusama, and is ready to go 🚀. Read about fast unstake [here](https://forum.polkadot.network/t/path-to-fast-unstake-in-polkadot-kusama/1539) or [here](https://twitter.com/Polkadot/status/1625550205960523780).

4. Increasing the number of validator candidates **from 1200 to 1500** in anticipation of an increase in the active set of validators

5. **Increasing the number of pools to 256**: given the successful launch of Pools so far on Polkadot, and the network having almost the full list of 128 pools, I propose doubling the maximum count again to 256.

Please nots this is submitted as an external motion: meaning if/after Council approves, the proposal will need to be up for vote by the community in referenda queue for the final decision. 

Make sure to vote at your convenience!

Schedule a majority-carries referendum to be tabled next once it is legal to schedule
an external referendum.

The dispatch of this call must be `ExternalMajorityOrigin`.

- `proposal_hash`: The preimage hash of the proposal.

Unlike `external_propose`, blacklisting has no effect on this and it may replace a
pre-scheduled `external_propose` call.

Weight: `O(1)`

Send a batch of dispatch calls.

May be called from any origin except `None`.

- `calls`: The calls to be dispatched from the same origin. The number of call must not
  exceed the constant: `batched_calls_limit` (available in constant metadata).

If origin is root then the calls are dispatched without checking origin filter. (This
includes bypassing `frame_system::Config::BaseCallFilter`).

# <weight>
- Complexity: O(C) where C is the number of calls to be batched.
# </weight>

This will return `Ok` in all circumstances. To determine the success of the batch, an
event is deposited. If a call failed and the batch was interrupted, then the
`BatchInterrupted` event is deposited, along with the number of successful calls made
and the error of the failed call. If all were successful, then the `BatchCompleted`
event is deposited.
