[MRESOLVER-367] Update Redisson and related documentation (#296)

This PR updates only redisson module: redisson dependency, simplifies 
installation by providing a "bundle" ZIP and updates site page.

Upgrade:
* redisson 3.21.3

Furthermore, replace "manual installation" (downloads dependency by dependency) with a "bundle" zip that contains all the dependency user needs to extract into lib/ext/redisson. Update doco accordingly.

 - Start your Redis instance on `localhost` or configure a remote instance with `${maven.conf}/maven-resolver-redisson.yaml`.
 - Now start a multithreaded Maven build or multiple builds (e.g., CI server) on your project.
