This is a proposal for four parachains to open HRMP channels with Statemint. Each channel opening consists of:

- A `forceTansfer` of 20 DOT from the Treasury to Statemint sovereign account.
- A `forceOpenhrmpchannel` from Statemint (1,000) to `ParaID`.
- A `forceOpenhrmpChannel` from `ParaID` to Statemint (1,000).

ParaIDs for each parachains requesting the channels and proposals requesting this by the parachain teams:

Litentry: 2,013
Composable: 2,019
Polkadex: 2,040
Zeitgeist: 2.092

Send a batch of dispatch calls.
Unlike `batch`, it allows errors and won't interrupt.

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 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>



- Proposal to open HRMP Channels between Statemint and 4 parachains (Litentry, Composable, Polkadex, Zeitgeist)
- Each channel opening consists of 20 DOT from the Treasury to Statemint and two `forceOpenhrmpChannels` - one from Statemint to the respective ParaID, and one from the ParaID to Statemint
- ParaIDs for each parachain: Litentry = 2.013, Composable = 2.019, Polkadex = 2.040, Zeitgeist = 2.092
