RFR: 7903889: jcstress: document used properites (and env variables) [v4]

[Jiří Vaněk]

> The purpose of this PR is to move properties and properties based initializations to single place, and to document them, and to enable printing the listing with the documentation via help.
> 
> No Env. vars were found.
> 
> The verbose help can be removed, the individual properties with defaults can be wrapped to its class. Even the OptionSpec and OptionFormatter can be used if needed
