Subject: [PATCH] Add P<>K bridge manual zombienet test for asset transfer
 (#198)

- [x] Does not require a CHANGELOG entry

This PR adds a P<>K bridge zombienet test which checks the following:
- transfering DOT from AssetHub Polkadot to AssetHub Kusama works
- transfering wDOT from AssetHub Kusama to AssetHub Polkadot works
- transfering KSM from AssetHub Kusama to AssetHub Polkadot works
- transfering wKSM from AssetHub Polkadot to AssetHub Kusama works

The test is meant to be ran manually as per the instructions in the
`README.md` and is based on the naive bridge testing "orchestrator"
defined in the `polkadot-sdk` repo:
https://github.com/paritytech/polkadot-sdk/tree/master/bridges/testing .
The "orchestrator" is downloaded using `git sparse checkout` directly
from the `polkadot-sdk` repo (I couldn't find a better way to package
the `bash` and `js` files on which the test depends).

Proposing to add the test in this repo as per the feedback from the
bridges team and since this way it would be more convenient to run it
before a release or when performing a change to the bridge hubs for
example. If there are concerns about this, the second option would be to
add it to the `parity-bridges-common` repo.

Closes: https://github.com/paritytech/polkadot-sdk/issues/3400

+# Bridges Tests for Local Polkadot <> Kusama Bridge
+
+This folder contains zombienet based integration test for both onchain and offchain bridges code.
+The tests are designed to be run manually.
+
+To start a test, you need to:
+
+- download latest [zombienet release](https://github.com/paritytech/zombienet/releases) to 
+`~/local_bridge_testing/bin/zombienet`.
+
+- build Polkadot binary by running `cargo build -p polkadot --release` command in the
+[`polkadot-sdk`](https://github.com/paritytech/polkadot-sdk) repository clone.
+
+- build Polkadot Parachain binary by running `cargo build -p polkadot-parachain-bin --release` command in the
+[`polkadot-sdk`](https://github.com/paritytech/polkadot-sdk) repository clone.
+
+- ensure that you have [`node`](https://nodejs.org/en) installed. Additionally, we'll need globally installed
+`polkadot/api-cli` package (use `yarn global add @polkadot/api-cli` to install it).
+
+- build Substrate relay by running `cargo build -p substrate-relay --release` command in the
+[`parity-bridges-common`](https://github.com/paritytech/parity-bridges-common) repository clone. Copy the binary to `~/local_bridge_testing/bin/substrate-relay`.
+
+- add the `sudo` pallet to the Polkadot and Kusama runtimes and give sudo rights to Alice. With this change build 
+the chain spec generator by running `cargo build --release -p chain-spec-generator --features fast-runtime` 
+command. Copy the binary to `~/local_bridge_testing/bin/chain-spec-generator`.
+
+- change the `POLKADOT_BINARY` and `POLKADOT_PARACHAIN_BINARY` paths (and ensure that the nearby variables
+have correct values) in the `./run-test.sh`.
+
+After that, you can run `./run-tests.sh <test_name>` command.
