Add block pruning support

[erikgrinaker]

Summary

Support for block pruning was added to Tendermint in 0.33.4, via the Commit.RetainHeight ABCI response field. It was decided to only support this via ABCI, and it is entirely up to applications to expose this functionality via e.g. configuration options or other mechanisms. The SDK should support this in some form.

See RFC-001 for background and considerations.

Is there any timeline for this issue?

I would try to get it into the next release. It is a highly requested feature

It's just 3-4 file config change. I'll knock this out.

nvm, I spoke too soon. This is a bit more complicated. But I still think we can knock this out.
