Should we make the API field names more consistent with the node configuration?

[emschwartz]

We are making a number of breaking changes in #236 to make the naming of config parameters more consistent. Is it worth making a bunch of breaking changes to the API to make the field names more consistent as well? For example, http_endpoint could be http_server_url and btp_uri could be btp_server_url

I'm fine with that. Let's also use that PR as a chance to split out the btp_uri into btp_outgoing_token and btp_server_url (to avoid having to prefix the URI with credentials)

I'd say it's now or never. 👍
