GEODE-10206: clean up product references to CMS (#7646)
* the command line validator no longer warns if CMS is not configured if the
JDK does not support CMS
* cleaned up comments that refer to CMS
> Geode assumes CMS garbage collector, which JDK 17 lacks

> Key: GEODE-10206
> URL: https://issues.apache.org/jira/browse/GEODE-10206
> Project: Geode
> Issue Type: Improvement
> Components: core, docs, gfsh
> Affects Versions: 1.15.0
> Reporter: Dale Emery
> Assignee: Darrel Schneider
> Priority: Major
> Labels: Java17, pull-request-available
>
> 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
