Rework KbsUri crate?

[fitzthum]

We have a KbsUri crate that handles constructing, serializing, deserializing, etc KBS URIs. This is kind of useful, but this is not how we figure out where to send requests. The KBS URI actually implements serialization into a URL, but this URL follows the KBS URI spec. This is not the same as the URL we send a request to.

In addition to the serialization in the KBS URI crate, we construct the URL for the Trustee request manually in several places. For example, the RCAR client does this.

let mut remote_url = format!(
    "{}/{KBS_PREFIX}/resource/{}/{}/{}",
     self.kbs_host_url, resource_uri.repository, resource_uri.r#type, resource_uri.tag
);

Maybe we should consolidate this logic into one place and have the KBS URI crate be able to produce the Trustee URL directly? On the other hand, perhaps the KBS URI logic is supposed to be generic and shouldn't have anything to do with Trustee. Since this isn't too important either way, I have just made this as an issue for now.
