How to remove shared data key using rust?

[leandrocurioso]

I am building a rust filter and using the shared data, I noticed that we have implementations of:

https://github.com/proxy-wasm/proxy-wasm-rust-sdk/blob/main/src/traits.rs#L32

get_shared_data and set_shared_data

I need a way to delete the key. I couldn't find a function do do that.

Can someone please share an example?

Thanks in advance!

set_shared_data(key, None, None) can be used to delete the key, but knowing this is a low-level ABI detail and it shouldn't be leaked to the SDK, so I've added remove_shared_data() (#307).

Note that some hosts will remove the key (e.g. NGINX), while others will only remove the key's value (e.g. Envoy).
