Issues in readme for microprofile-rest-client QS

(1) WF BOM is used instead of EAP one:

        <groupId>org.wildfly.bom</groupId>
        <artifactId>wildfly-microprofile</artifactId>
        <version>${version.server.bom}</version>

(2) References to WF instead of EAP, e.g.:

<!-- Import the MicroProfile REST Client API, we use provided scope as the API is included in WildFly -->

These references are used in pom.xml as well.

(3) QS contains tests but the readme does not mention them.

(4) Consider using standard sections:

• Use of the EAP_HOME and QUICKSTART_HOME Variables
• Undeploy the Quickstart
• Run the Arquillian Tests
• Run the Quickstart in Red Hat JBoss Developer Studio or Eclipse
