MP-3528 pass external routes to swapper (#352)

* Init swapper extraction.

* Integrate new swapper logic into CM.

* Revert "Integrate new swapper logic into CM."

This reverts commit 68d3047a00368fe3a95c03effb9d04d4fab0b4cf.

* Pass SwapperRoute from CM (and RC) to Swapper contract.

* Clean swapper aimed to be managed by feature flags.

* Fix tests.

* Make fallback to routes in state if no route provided.

* Update schema.

* Increase number of swaps for TWAP tests.

* Make RC swapping backward compatible. Use state routes if not provided.

* Make swapper params more consistent between Astro and Osmo.

* Add custom config for swapper.

* Update schema.

* Review comments.

* Revert wasm file path.

* Migration.

* Add validation for config.
