We propose to make use of the new auto-renew feature on the coretime systemchain. This will send an XCM call to coretime and transact a `broker.enableAutoRenew` call for our current core 16 and our paraid 2015

The [last attempt](https://integritee.polkassembly.io/motion/65) had errors not only in the transact call at its destination but also an outdated XCM version on our chain and a missing HRMP channel to coretime. This new batch call cleans it all up and has been tested with chopsticks:

1.  set default XCM version to V3
2.  open HRMP channel to coretime
3.  send a noop XCM (only to help debugging)
4.  transact on coretime to enable auto-renew

This proposal announces the successful completion of an initiative to deliver an MVP for a UI Kit, which has been deployed and tested on Westend and Rococo networks.

Publishing 144 articles on Polkadot-related topics and distributing them across multiple platforms.

Hosting 30 live streams covering various topics like Paracha in progress Updates, Community AMA, Proposal Progress Updates, and Polkadot 101 sessions.

Producing 24 educational videos about infrastructure projects, parachains, and ecosystem diversity.

Conducting interviews with 12 parachains or eco-projects, editing them into videos, and sharing them on social media platforms.

Schedule a majority-carries referendum to be tabled next once it is legal to schedule
an external referendum.

The dispatch of this call must be `ExternalMajorityOrigin`.

- `proposal_hash`: The preimage hash of the proposal.

Unlike `external_propose`, blacklisting has no effect on this and it may replace a
pre-scheduled `external_propose` call.

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`).

## 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.

- **Problem Statement:** Implementing the auto-renew feature on the coretime systemchain for core 16 and paraid 2015.
- **Significance:** Resolving errors from previous attempts and updating XCM version and HRMP channel for smoother transactions.
- **Proposed Solution:** Utilize a new batch call to set XCM version to V3, establish HRMP channel to coretime, send a noop XCM, and transact on coretime to enable auto-renew.
- **Expected Outcomes:** Improved functionality, error resolution, and streamlined auto-renew process on the coretime systemchain.
