Alarms package documentation refers to node-cron rather than cron

[hassenius]

The documentation for the alarms package refers to the format of node-cron (for example second field is optional)
https://github.com/openwhisk/openwhisk/blob/master/docs/catalog.md#firing-a-trigger-event-periodically

However, looking at the source, alarms uses the cron package:
https://github.com/openwhisk/openwhisk-package-alarms/blob/master/package.json
Which seems to require 6 fields, etc

Cron package documentation
https://www.npmjs.com/package/cron
