function drush_hosting_dispatch in Hosting 6.2

Same name and namespace in other branches

1. 7.4 dispatch.hosting.inc \drush_hosting_dispatch()
2. 7.3 dispatch.hosting.inc \drush_hosting_dispatch()

Main queue processing drush command for hostmaster.

This is a single command, which will (based on configuration) run all the other queue commands (cron, backup, tasks, stats). This is done so that there is only one cron job to configure, and allow the frequency of calls to be configured from the frontend interface.
