Don't use retries for puppet deployments by default
Don't use retries for puppet deployments by default

Granular deployment task with possibility for user
to control number of retries for any task now allow
Astute to decrease number of retries from 1 to 0 by default.

It will give us such benefits:

* fail fast: do not use useless retries for failed task;
* detect cases where we need to place retries inside task code;
* show us tasks with bad design from box.

For special it could be setup by hands.
