Delete some unused configurations.

@girazoki hi, can you give me some feedback.

@99Kies the CI returned this error:

  error[E0432]: unresolved import `super::WeightToFee`
    --> /home/gh-actions/runner/_work/moonbeam/moonbeam/runtime/moonriver/src/xcm_config.rs:22:66
     |
  22 |     ParachainInfo, ParachainSystem, PolkadotXcm, Runtime, Treasury, WeightToFee, XcmpQueue,

It seems an import that was removed was used in xcm_config.rs. So add it back please.

This will be used again $soon in #1218 (which is waiting for an upstream Substrate PR). It may still be a while before that can be done, though, so removing this is fine for now.

@99Kies CI 返回了这个错误：

  error[E0432]: unresolved import `super::WeightToFee`
    --> /home/gh-actions/runner/_work/moonbeam/moonbeam/runtime/moonriver/src/xcm_config.rs:22:66
     |
  22 |     ParachainInfo, ParachainSystem, PolkadotXcm, Runtime, Treasury, WeightToFee, XcmpQueue,

似乎在 xcm_config.rs 中使用了已删除的导入。所以请加回来。

oh, I lost this problem, sorry.

[girazoki]

Yeah actually I missed the error because the build wasnt running. So it is being used in xcm

[99Kies]

@girazoki In fact, I noticed that transaction_payment does not use the WeightToFee.
So now WeightToFee is mainly used in XCM. Does transaction_payment need to be modified.

[girazoki]

For now, no. We need to give a good think on what values we want for transaction-payment, and until this is decided, WeightToFee will only be used in xcm

Closing since this item is used. It will be used more in the future, as noted.
