extract_contracts is not documented

[airled]

Hi. I see that cli has extract_contracts function but I don't see any mentions in the documentation about it. What is the reason? Doesn't it work properly?

@airled I tried this extract_contract command and it worked without any issue. However, before trying this command, you need to apply this patch #400 in order to populate trace statuses.

Also, make sure that you are using a full sync archived Geth client node as the provider
