Added Polkadot <> Kusama bridge configuration (polkadot-fellows#108)

This PR adds bridge configuration to allow exchanging assets between Polkadot and Kusama Asset Hubs. So far we only support sending KSM from Kusama Asset Hub to Polkadot Asset Hub as wKSM + DOT from Polkadot Asset Hub to Kusama Asset Hub as wDOT. Other assets may be added later. The opposite direction is also supported, though it'll need dependencies upgrade to >= v1.4. --- Similar Rococo <> Westend bridge is also active on live chains. You may read docs on how to play with it here: https://github.com/paritytech/polkadot-sdk/blob/master/cumulus/parachains/runtimes/bridge-hubs/README.md For Polkadot <> Kusama bridge we have a dedicated branch for local zombienet tests: https://github.com/svyatonik/runtimes/tree/sv-pk-bridge-with-zombienet-tests. You may run autotests (exchanging assets) there - see https://github.com/svyatonik/runtimes/blob/sv-pk-bridge-with-zombienet-tests/system-parachains/bridge-hubs/zombienet/README.md for details. You may do manual tests by spawning local chains using those scripts and use https://github.com/svyatonik/runtimes/blob/sv-pk-bridge-with-zombienet-tests/system-parachains/bridge-hubs/zombienet/scripts/bridges_kusama_polkadot.sh script to run various commands - i.e. send assets manually. Polkadot js apps is also supported. --------- Co-authored-by: Branislav Kontur <[email protected]> Co-authored-by: Bastian Köcher <[email protected]>
