Acala Foundation have registered para id 2233 and won a parachain slot auction by bidding with the intention to use the new lease to renew Karura para lease.

However, due to historical reasons and missing migrations, para id 2233 is locked and in a bad state that can only be managed by root track.

In order to fix the bad state and improve the parachain lock mechanism to ensure this cannot happen in future, I have proposed [RFC-14](https://github.com/polkadot-fellows/RFCs/pull/14). A draft implementation is also implemented: https://github.com/paritytech/polkadot/pull/7560.

But Polkadot Fellowship is still on the process of taking over the ownership of Polkadot runtime, which slows everything down. We do not know if the RFC-14 can be accepted, implemented, and enacted before lease 32 ends.

As a result, I would like to perform a lease swap between Karura (Para ID 2000) and Para ID 2233 with root track. 

Once RFC-14 is enacted, we would be able to self-service the lease swap in future and other parachain teams will be less likely require root track governance intervene for least swap or state update.

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`).

## Complexity
- O(C) where C is the number of calls to be batched.

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.

- Acala Foundation won a parachain slot auction and wants to renew their lease for Karura para.
- The para id they won is in a bad state and can only be fixed by root track.
- They have proposed a solution to fix the bad state and improve the parachain lock mechanism.
- The process is slowed down because the Polkadot Fellowship is taking over the ownership of Polkadot runtime.
- They want to perform a lease swap between Karura and the para id to fix the issue.
