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 the currently externally-proposed majority-carries referendum to be tabled
immediately. If there is no externally-proposed referendum currently, or if there is one
but it is not a majority-carries referendum then it fails.

The dispatch of this call must be `FastTrackOrigin`.

- `proposal_hash`: The hash of the current external proposal.
- `voting_period`: The period that is allowed for voting on this proposal. Increased to
	Must be always greater than zero.
	For `FastTrackOrigin` must be equal or greater than `FastTrackVotingPeriod`.
- `delay`: The number of block after voting has ended in approval and this should be
  enacted. This doesn't have a minimum amount.

Emits `Started`.

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.

- The proposal wants to make changes to three operations on Polkadot.
- They want to increase the minimum number of tokens required to create a nomination pool and become a direct nominator.
- They also want to enable fast unstake on Polkadot.
- They want to increase the number of validator candidates and the number of pools.
- The proposal needs to be approved by the Council and then voted on by the community.
