Containers of same type use same package name

All JBoss AS containers (remote/local/embedded 51|60) use the same package name org.jboss.arquillian.jboss.

This causes some problems:

• Some use the same ClassNames(JBossASContainerConfiguraiton) so having them on the same classpath is impossible
• Configuration mapping is based on package name to ContainerConfiguration impl. With the same package name it will be impossible to have two JBoss AS(1 local and 1 remote) containers in the same configuraiton file with different options(which to choose). The containers even have different configuration options, so it will fail if it tried to random pick one.
