-----------------------------------
Issue Type: Task (was: Bug)
> Services should be able to specify that credential store is always enabled
> --------------------------------------------------------------------------
>
> Key: AMBARI-20136
> URL: https://issues.apache.org/jira/browse/AMBARI-20136
> Project: Ambari
> Issue Type: Task
> Components: ambari-server
> Affects Versions: 2.5.0
> Reporter: Sumit Mohanty
> Assignee: Sumit Mohanty
> Priority: Critical
> Fix For: 2.5.0

> At this point, credential store can be enabled or disabled for a service.
> Some services, such as Ranger and LogSearch should be able to indicate that
> CS cannot be disabled. The eventual goal is to always have CS enabled for all
> services that support credential store.
> Current metainfo.xml has the following section
> {code}
> <credential-store>
> <supported>true</supported>
> <enabled>false</enabled>
> </credential-store>
> {code}
> We need to add a notion of required. A third element called "required" may be
> added. We can potentially, create an enum for a new field "supportType" and
> collapse "supported" and "required" but that, while succinct, does not help
> much in readability.
> {code}
> <credential-store>
> <supported>true</supported>
> <required>false</required>
> <enabled>false</enabled>
> </credential-store>
> {code}
> The above means, CS is supported, not required, and not enabled. "false" is
> the default for *required*.
> For services that require CS support
> {code}
> <credential-store>
> <supported>true</supported>
> <required>true</required>
> <enabled>true</enabled>
> </credential-store>
> {code}
> Service create logic should set the CS-enabled flag to be true if *required*
> is true independent of what *enabled* says. *required* flag is not needed in
> the service resource REST API but the stacks API should provide access to
> this flag.
> API to disable CS should throw an error if *required* is true.
