Unable to create redirect_prefix without specifying a full URL

[Nguyen Ngoc Hieu]

I want all my requests to be redirected with the path '/api/v1' as instructed by HAProxy [https://www.haproxy.com/documentation/haproxy-configuration-tutorials/http-redirects/#redirect-traffic-using-a-prefix], but it seems Octavia API does not allow that. The redirect_prefix attribute is validated according to URLType instead of URLPathType, is there a reason for this?

I can submit a patch if this is confirmed.

To summarize, you would like to be able to do something like:

openstack loadbalancer l7policy create --action REDIRECT_PREFIX --redirect-prefix /api/v2 --name l7p1 listener1
openstack loadbalancer l7rule create --compare-type STARTS_WITH --type PATH --value /api/v2 --invert l7p1

Right now --redirect-prefix /api/v2 is rejected because it doesn't contain a scheme or an hostname

Let's discuss it with the team, I don't know if there's a reason to not allow it.

Yup, that's exactly what I mentioned.
