  - cosmwasm-std: Make `CustomQuery` a subtrait of `Clone`, i.e. types that
  implement `CustomQuery` need to be `Clone`able.
  -- cosmwasm-std: Remove `Copy` implementation from `QuerierWrapper` and `Deps`
  - which is not derived for custom non-`Copy` query type `C`. Both types are too
  - complex to guarantee `Copy` conformance long term, even if they are cheap to
  - clone right now.
  - cosmwasm-std: Add generic for custom query type to `QuerierWrapper`, `Deps`,
  `DepsMut` and `OwnedDeps`. Merge `QuerierWrapper::custom_query` into the now
  fully typed `QuerierWrapper::query`.
