Juan Ignacio Rios 8b3bf39ab8 Add HRMP notification handlers to the xcm-executor (#3696)
Currently the xcm-executor returns an `Unimplemented` error if it
receives any HRMP-related instruction.
What I propose here, which is what we are currently doing in our forked
executor at polimec, is to introduce a trait implemented by the executor
which will handle those instructions.

This way, if parachains want to keep the default behavior, they just use
`()` and it will return unimplemented, but they can also implement their
own logic to establish HRMP channels with other chains in an automated
fashion, without requiring to go through governance.

Our implementation is mentioned in the [polkadot HRMP
docs](https://arc.net/l/quote/hduiivbu), and it was suggested to us to
submit a PR to add these changes to polkadot-sdk.

Parachains

This directory is the home of Parity-developed parachain runtimes. This directory is runtime focused, and does not include builds of parachain nodes.

The general internal structure is:

  • chain-specs: Chain specs for the runtimes contained in its sibling dir runtimes.
  • common: Common configurations, impls, etc. used by several parachain runtimes.
  • integration-tests: Integration tests to test parachain interactions via XCM.
  • pallets: FRAME pallets that are specific to parachains.
  • runtimes: The entry point for parachain runtimes.

System Parachains

The runtimes directory includes many, but is not limited to, system parachains. Likewise, not all system parachains are in this repo.

Releases

The project maintainers generally try to release a set of parachain runtimes for each Polkadot Relay Chain runtime release.
