In WebrevStorage.java in mlbridge bot, there is a hardcoded reference to bugs.openjdk.org which is used to instantiate an IssueTracker to look up issues. This is pretty bad design and needs to be corrected. Having this hardcoded URL in the product code for mlbridge also has the side effect of the tests needing internet access to run.

The mlbridge bot configuration already takes an issuetracker URL used to generate issue links in emails. This URL should be replaced with a proper IssueTracker configuration. The IssueTracker interface then needs to provide a method for generating a webURL given an issueId so we don't need to actually lookup an issue to be able to generate the URL.

We may also need to extend the TestHost implementation to be able to adapt the existing mlbridge tests for this.
