> Currently, the Blueprint deployment process for a cluster will always take a component
through the "INSTALL" and "START" phases.  
> While this is the correct default behavior for most cluster deployments, there are cases
where a user would like more fine-grained control over when certain components are started.

> There is currently some support for this, implemented by AMBARI-14283, however this support
is currently cluster-wide, so that START commands can be disabled for the entire cluster,
but not on a component-basis.
> I propose that we extend the work in AMBARI-14283 to also allow a Blueprint to specify
that certain components may only use the "INSTALL" phase, and skip the "START" phase.  
> This work will require some minor additions to the Blueprint syntax, that I'll publish
in this proposal.  
> The Blueprint syntax should support marking each comopnent as having a "provision_action"
that can override the default "INSTALL_AND_START" behavior.
