Match issue types schema using project key on JIRA Server

What does this MR do?

This MR changes the way we integrate with JIRA Server

On JIRA Cloud, rest/api/2/issuetypescheme/project would give you issue type schema for the active project. But when using JIRA Server you can have multiple projects. As such, we need need to lookup the project using project key and then fetch the issue type scheme active for the given project.
