The simulatir tool can be used either to virtually
run the deployment to find out the task run order
or to plot the entire graph or its subset.

Several changes:
- support fault tolerance group;
- support internal stop deployment instead of raise in
case of error;
- do not show last run summary debug report from mcollective;
- fix support of detecting offline nodes before run deployment;
- support fail on error behavior.
Support fault tolerance group
Nailgun send fault tolerance group which inform Astute about
available number of error nodes in this deployment and importance
of every node in this task.
If number of error exceeds number of available errors, deployment
will stop.
Support internal stop deployment instead of raise in case of error
Before this change Astute is end processing, marks all nodes
as error and do not waiting of puppet process on nodes.
Now we use same way that used in case of stop deployment.
Mark failed nodes as error, another nodes as skipped(stopped),
ready nodes as ready. Also Astute will wait before current
tasks end.
Do not show last run summary debug report from mcollective
For now moment it not so useful, but quickly filled log file
and difficult debug process
Fix support of detecting offline nodes before run deployment
Astute gets response from mcollective to detect node availability.
If node do not respond, it will mark as failed. It also support
fault tollerance mechanism
Support fail on error behavior
From this moment task which setup fail_on_error if false,
task marks as skipped instead of failed in case of error.
