test: add liquid assets script to test network

[bee344]

Two questions I have regarding this:

• Currently I have to force pjs to accept <any> when dealing with the asset-conversion-pallet, because the types it expects come from the substrate-node implementation and are incompatible with the Kusama Asset Hub implementation, but due to this I have to disable eslint for those two lines.

const createLiquidityPoolCall = (api: ApiPromise) => {
	// For now, we have to override the types of the Assets until PJS is updated
	// eslint-disable-next-line @typescript-eslint/no-unsafe-argument
	return api.tx.assetConversion.createPool(<any>native, <any>asset);
};

const addLiquidityCall = (api: ApiPromise, amountNative: number, amountAsset: number, to: KeyringPair) => {
	// For now, we have to override the types of the Assets until PJS is updated
	// eslint-disable-next-line @typescript-eslint/no-unsafe-argument
	return api.tx.assetConversion.addLiquidity(<any>native, <any>asset, amountNative, amountAsset, 0, 0, to.address);
};

• Trappist doesn't support asset-conversion so all the process runs on KAH, wondering how we feel about that.

Edit: Issue to add asset-conversion to trappist.
Edit 2: Types on PJS that are used on Asset Conversion

This is totally fine with me. I double checked the ts compilter issue happening with PJs and this is the right approach.

[TarikGul]

Same with this, totally fine.

I think this should be totally fine, not much we can do. That being said if we can still create the liquid pool assets thats a step forward. In this case though we just can't transfer them to Trappist if I understand this correctly?

Overall, amazing script. LGTM!

Correct, right now there's no way to send the LP tokens to Trappist, but we create them just fine and we can even send them between accounts, so that's ok.

Okay I think that's perfect then and the script does exactly what it intends on doing. Feel free to merge it in, whenever your'e ready
