title: JIRA: Searching for all issues with a given link type
body: <p>Is there a way to query for all issues with a particular link type?</p>
  
  <p>For example, let there be a dependency link where an issue can "depends on" another issue. Is there a query to find all issues that depend on some other issue (aka. all issues with the "depends on" link)?</p>
  
  <p>I know there is the <em>linkedIssues</em> (<em>key</em>, <em>linkType</em>) function that returns the key of all issues that have the <em>linkType</em> with the issue with <em>key</em>. I want to find all issues with a <em>linkType</em> with any issue.</p>
  
  <p>Thanks!</p>
