CliCommandBuilder.of method must be added back

This has been caused by: https://issues.redhat.com/browse/WFCORE-5873

in which the of methods have been removed.

It happens that the Galleon plugins rely on the "of" method when applying finalize CLI scripts. This has been hidden in wildfly testsuite because no CLI scripts are executed.

In the context of the wildfly-cloud-galleon-pack we have the case. Again this has been hidden due to the fact that the wildfly-maven-plugin uses a old version of the launcher API in its classpath (that contains the "of" method).

This problem has been found when using pure galleon maven-plugin to provision the wildfly-cloud-galleon-pack. An upgrade of the wildfly-maven-plugin dependency on core would also reveal the problem.
