Rewrite client handling (#1531)

* Rewrite client handling

We are supporting muliple polkadot-like chains and all have different
client types. This pr reworks the client handling by having all of them
in one enum combined. Besides that, there is added a special trait
`ExecuteWithClient` to use the internal client.

* Apply suggestions from code review
