Branch arquillian

Hi Arun,

this is the first pull request so that you can check that we are on the right path. In this pull request you will find the necessary changes on the pom.xml file of the javaee7-samples parent project which contains the necessary changes for the Arquillian to be configured for all the subprojects and also necessary changes in order to be able to use wildfly with full profile using arquillian container support. The latter may set the cargo maven plugin as not mandatory anymore since most of the appservers are already supported by arquillian. Currently there is only one problem with an exception in the test, I found that it was reported as bug but they say is solved. I work on that. The tricky part was the configuration.

regards
Nick
