XCM WeightTrader: Swap Fee Asset for Native Asset (#1845)
Implements an XCM executor `WeightTrader`, facilitating fee payments in
any asset that can be exchanged for a native asset.
A few constraints need to be observed:
- `buy_weight` and `refund` operations must be atomic, as another weight
trader implementation might be attempted in case of failure.
- swap credit must be utilized since there isn’t an account to which an
asset of some class can be deposited with a guarantee to meet the
existential deposit requirement. Also, operating with credits enhances
the efficiency of the weight trader -
