Cloned from JBEAP-8206 for 7.0

Artemis as project using word embedded to express that Artemis can be added to any application and instantiated programatically in the code [1]. We don't not support it from EAP 7 point of view and we should avoid any confusion in the naming.

It would be better to say that Artemis is integrated in EAP 7 rather than embedded in all occurrences in Configuring Messaging [2]. For example chapter Chapter 2. The Embedded ActiveMQ Artemis Messaging Broker should be renamed to Chapter 2. The Integrated ActiveMQ Artemis Messaging Broker and so on.
