> h3. Background
> HDDS-16640 made the KeyLifecycleService properties reconfigurable at runtime.
> Doing that needed several pieces of hand-written plumbing:
> - {{{}KeyLifecycleService.OZONE_KEY_LIFECYCLE_PROPERTIES{}}}, a
> hand-maintained set of property keys used to register reconfiguration
> handlers in {{{}OzoneManager{}}}.
> - {{{}KeyLifecycleService.ReconfigurableSettings{}}}, which reads every
> property from {{ConfigurationSource}} and checks it.
> - Per-property handlers ({{{}validateKeyLifecycleProperty{}}}) that only
> validate, plus a complete callback that re-reads the full configuration.
> The keys and defaults are also defined separately: as constants in
> {{{}OMConfigKeys{}}}, with descriptions in {{{}ozone-default.xml{}}}. Adding
> or changing a lifecycle property means updating all of these places.
> h3. Proposal
> Move all {{ozone.lifecycle.service.*}} properties into a new {{@ConfigGroup}}
> class, {{{}KeyLifecycleServiceConfig{}}}, that extends
> {{{}ReconfigurableConfig{}}}, following the existing {{OmConfig}} pattern.
