…ethods.

 - Yank all statements and delete functions as needed.
 - Make any required functions from types/ public.
 - Add the vm in the 08-wasm keeper.
 - Update documentation to include documentation of deleted functions.

 - Refactor signatures to explicitly pass vm, client identifier for time being.
 - Refactor tests to conform with new signatures.
 - Replace occurences of `ibcwasm.GetVM` in other keeper functions.

- Matches moves for other functions.
- Move is required to address future circular dependency for state management (keeper would import types and types would import keeper)
- Rm migrate_contract(test).go files.

- Remove globals for state (Checksums)
- Move access functions from types to keeper, move tests.
- Update calls using global to instead go through keeper.

This previously was testing a function that didn't set the client state after calling the contract (invoking through the keeper
always sets a client state after contract invocation). Hence, even if we don't set explicitly in the migrateFn callback, we _still_ get
a client state in the end.

 - Move into the func for creating new plugins, pass it to acceptStargateQuery directly. This is probably what wasmd did (see they don't accept a query router now?).
   Since we don't use the get elsewhere, this was the smallest diff for a globa.
 - Preemptively ran make lint-fix, gotcha linting crybaby.

…in export_test.go for types/.

- Remove generic types and do unmarshalling in light client methods.
- Move all functions onto keeper and adjust call sites.

…e to light client tests.

- Consistently use wasmClientKeeper as local var name.
- Reorg keeper fields slightly.
- Rm 'vm.go' which was already empty.
