Issue Summary

The JQL integration returns only the first 50 issues. This is the default number of issues returned via JIRA REST API. A mechanism should be implemented where a query is executed multiple times to fetch subsequent issues from JIRA.

Steps to Reproduce

1. Configure JIRA integration
2. Create any JQL query which returns more than 50 issues
3. Execute the query

Expected: More than 50 issues returned.
Actual: Only 50 issues returned.
