HAWKULAR-70: Metrics Alerts page

[vrockai]

When you add new URL, two triggers (threshold & availability) are created for newly created metrics. These are easily configured in the Setup tab. To see some alerts, try to setup the values for threshold to 10ms for 1s. Wait 30 seconds and reload the alerts page. Be aware the alerts page cannot be accessed from the submenu now, but you have to make them metrics aware, like:
http://localhost:2772/metrics/alerts/x1427307245678

Notes:

• Added angular-patternfly, because it contains the directive for patternfly select widget. Be sure to delete your lib folder and run bower install again.
• Added dependency to bootstrap.js, but only to the index.html, not to the bower. Unfortunatelly, the directive for select (or the patternfly select itself, not sure) is dependent on jquery and bootstrap.js. I will need to fix this in a future, but this may be time consuming, so putting those links into index.html is a temporary workaround. We need to put them by hand into console index.html, too.
• Contains a temporary workaround for the "time unit" selector, since original design used bootstrap one instead of patternfly one.
