Code Issues Proposed changes

Fix join examples and text

Browse Source 
The 'join' example for using a number did not have a proper workflow.
It looks like it was copied from the 'all' example and not completely
changed. Also, disambiguate the wording of the description for that
example. It used the word 'once' in a place where it looked as though
it meant 'one time' instead of 'as soon as'.

When a task has property "join" assigned with a numeric value then the task
will run once at least this number of upstream tasks are completed and
will run when at least this number of upstream tasks are completed and
corresponding conditions have triggered. In the example above task
"wait_for_two_registrations" will run if two any of
"register_vm_xxx" tasks complete.
