Feature Request: OpenApi import: support $ref remote reference

[rzorzorzo]

example: https://gitlab.ow2.org/bonita/bonita-openapi/-/tree/master currently there is no way of importing this openapi spec into yajsw.

import of the entry point openapi/openapi.yaml causes the following error:

java.lang.RuntimeException: Unable to load RELATIVE ref: ./paths/loginservice.yaml path: /tmp

Suggestion: allow import of a .zip file with input of relative path to the entry point file.

This also raises the general question of support for http uris. I think that supporting http uris could lead to security issues or require authentication.

Will look into it. Since resolving HTTP could lead to security issues, we probably just start with the .zip file approach.
