Fixes KILTprotocol/ticket#3467. Not meant to be merged until all other stacked PRs will be merged into this. Adds the first round of features to the swap pallet, specifically it includes a swap pool that supports only the runtime local currency, swappable 1:1 (not configurable yet) with a configurable remote token. The XCM fees are paid in a local fungible token as injected by the runtime. The pallet also exposes two implementations of the `IsReserve` trait that must be added to the runtime to allow the configured tokens (to swap back to local currency and to pay for XCM fees) to be reserve-transferred to this chain. That code is not yet part of this PR. Additional TODOs for the pallet is both within the code where applicable, and in the pallet `README.md` file. --------- Co-authored-by: Adel Golghalyani <48685760+Ad96el@users.noreply.github.com> Co-authored-by: Adel Golghalyani <ad96el@gmail.com>
