> *Following attributes of configuration properties should be made stack API driven:*
> # Visibility of configuration property
> # display name of configuration property
> # Empty value validity of configuration property
> # Restriction of being configured only once on installation
> # overridable in config host group
> # Name of the property should be hidden
> *Achieving this task will be useful in following scenarios:*
> # custom services could be added with less changes in ambari-web code
> # Any issues related to configuration property attributes encountered on a deployed cluster
can be addressed by making stack changes rather than redeploying ambari-web code with a fix.
For example if a property tagged as not overridable if later desired to be made overridable
on a deployed cluster will now require changing a boolean flag in stack configuration property
rather than changing ambari-web code. 
> # Config property only in a specific stack can be attributed without writing stack specific
logic in ambari-web
