    Fix Version/s: 1.15.0

The erb doc files still need attention but that will be done on another ticket.

> Several places in Geode code and documentation assume that Concurrent Mark 
> Sweet (CMS) garbage collector exists, and that these VM arguments are 
> meaningful:
>  - -XX:+UseConcMarkSweepGC
>  - -XX:CMSInitiatingOccupancyFraction
> The CMS garbage collector is not available on JDK 17. JDK 17 warns that it 
> does not recognize these arguments.
> These production classes rely on CMS args at runtime:
>  - extensions/geode-modules: ResourceManagerValidator.validateSunArguments() 
> recommends configuring the CMS args.
>  - geode-gfsh: StartMemberUtils passes the CMS args when max heap is set.
> These test classes use the CMS args at runtime:
>  - geode-for-redis: OutOfMemoryDUnitTest passes a 
> CMSInitiatingOccupancyFraction arg when starting a server.
> User-facing Javadoc comments on these classes refer to the CMS args:
>  - geode-core: EvictionAttributes
>  - geode-core: ResourceManager
> Code comments in these classes refer to the CMS args:
>  - geode-modules: AbstractCache
> These properties files in geode-modules-assembly define or refer to the CMS 
> args:
>  - scripts/setenv.properties
>  - tcserver/geode-cs/configuration-prompts.properties
>  - tcserver/geode-p2p/configuration-prompts.properties
> These documentation files in geode-docs refer to the CMS args:
>  - configuring/running/running_the_cacheserver.html.md.erb
>  - managing/heap_use/heap_management.html.md.erb
>  - managing/monitor_tune/system_member_performance_garbage.html.md.erb
