Add remote proxy support to AH Kusama (#535)
This adds remote proxy support to AssetHub on Polkadot and Kusama. Currently it is configured only to support using proxies registered on the relay chain to work on AssetHub. In the future this can be expanded. --------- Co-authored-by: Xiliang Chen <xlchen1291@gmail.com> Co-authored-by: Branislav Kontur <bkontur@gmail.com> Co-authored-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io>
