Provide command in node-cli for cleaning the wasmer cache

[clearloop]

Problem to Solve

This could be sth in the future, for the network or our development

Possible Solution

make the cache path of wasmer configurable from the node client, make it a command

better to make it part of the data directory of the chain that we can use purge-chain to clean it together

Notes

No response
