**Summary**

This proposal from Pendulum aims to open an HRMP channel between Amplitude and Statemine and accept the request from Amplitude. 

**Details**

As is usual for opening HRMP channels, the extrinsic consists of a batch of two calls:

A 11 KSM force transfer from Kusama treasury (`F3opxRbN5ZbjJNU511Kj2TLuzFcDq9BGduA9TgiECafpg29`) to Statemine (`F7fq1jSNVTPfJmaHaXCMtatT1EZefCUsa7rRiQVNR5efcah`) to pay for fees and for the deposit. Send XCM message to Statemine to execute a transaction with superuser (root) permission.

Based on the past discussion - [Polkassembly discussion link](https://kusama.polkassembly.io/post/2040)

Send a batch of dispatch calls and atomically execute them.
The whole transaction will rollback and fail if any of the calls failed.

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.
