Look into adding support for xray v2 api

[JordanSussman]

As of Xray 2.4.x JFrog has started migrating endpoints from /v1/ to /v2. The specific notes from confluence are:

From version 2.4, JFrog Xray is introducing a new REST API version. The different endpoints specified in this page will be upgraded gradually over progressive version upgrades, while maintaining backward compatibility to previous API versions. Where new endpoints are available, the API Version will be listed. In these cases, you should make sure to use corresponding Base URL as specified below. If the API version is not specified, it means the endpoint is part of the V1 REST API and you should use the V1 base URL.
