Reload Jira Security Issue

This is a small library that can create Jira issues. The main idea is that it's simple to use and it'll not recreate an issue if the proper keys are supplied.

Quick example:

        $issue = new JiraSecurityIssue();

        $issue->setTitle('Issue title')
            ->setBody('The main body');

        $issue->setKeyLabel('some-unique-id');

        echo $issue->ensure();

Configuration is set using environment variables, for ease of use in CI systems.
