This proposal aims to open HRMP channel between Statemine & Calamari.

Let me explain the technical details of this call. It is a batch transaction with two calls:

1. A force transfer from Kusama treasury (`F3opxRbN5ZbjJNU511Kj2TLuzFcDq9BGduA9TgiECafpg29`) to Statemine (`F7fq1jSNVTPfJmaHaXCMtatT1EZefCUsa7rRiQVNR5efcah`). The amount is 11 KSM. 10 KSM will be used for deposit to accept (5 KSM) and open (5 KSM) HRMP channel. 1 KSM will be used by Statemine parachain to pay for transaction execution fee on Kusama. Note that 1 KSM is more than enough and unused funds will be refunded back to the Treasury account.
2. Send XCM message to Statemine to execute a transaction with superuser (root) permission. The XCM message to Statemine is `0x1f000101000214000400000000070010a5d4e81300000000070010a5d4e800060003005ed0b25c1800083c01240800003c0024080000e803000000900100140d01010000000004000101006d6f646c70792f74727372790000000000000000000000000000000000000000`, which can be decoded on Statemine, and it is polkadotXcm.send. It sends a XCM message back to Kusama, with 1 KSM for transaction fee and to perform a transact of call `0x1800083c01240800003c0024080000e803000000900100`. It will refund any unused funds back to the Kusama Treasury account `F3opxRbN5ZbjJNU511Kj2TLuzFcDq9BGduA9TgiECafpg29`

The call is is a batch call that accepts open channel request from Calamari, and make an open channel request to Calamari.

Send a batch of dispatch calls.

May be called from any origin.

- `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 call are dispatch 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.
