This is a call to register the Coretime parachain. Once registered, the rest of the Kusama system can upgrade to v1.2.0, migrating all leases to Coretime. A separate referendum will start the sale of Coretime via the Coretime chain.

This is based off of the Coretime runtime in the [Fellowship v1.2.0 release](https://github.com/polkadot-fellows/runtimes/releases/tag/v1.2.0).

This proposal by Subsquid Lab Official seeks funding for ongoing development and maintenance of Subsquid Archives and the Giant Squid API, vital components of Polkadot and Kusama data infrastructure. Archives provide GraphQL access to on-chain data for various parachains, supporting projects like Polkassembly and Talisman. The ArrowSquid release enhances real-time processing and decentralizes Archives. In Q3 2023, Subsquid served over 1.46 billion queries, indicating significant usage.
