[CD 17] Configuration guide - intercorporate infinispan 9.x eviction changes and add eviction description

In Configuration guide, chapter Infinispan, subchapter 23.3.2. Cache Containers:
https://doc-stage.usersys.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/7.1/html-single/configuration_guide/#cache_containers

There is Example: Default Infinispan Configuration, which shows:

<eviction strategy="LRU" max-entries="10000"/>

"strategy" and "max-entries" attributes were deprecated and "size" attribute should be used instead.

Also please document eviction feature itself, as I could not find anything about it in the guide.
