Test migration path for renaming Ajocado to Graphene

Run any available tests (Metamer, RF Showcase, ...).

I have already checked that these are compilable,
but additionally we need to make sure that it's working at runtime.

Let's trigger several tests (not necessarily whole test suite) from each sample test project.

Migration path:

• rename Maven groupIds to ajocado->graphene
• rename Maven artifactIds ajocado->graphene
• additionally arquillian-ajocado-junit was renamed to arquillian-graphene-junit-container (ARQAJO-121)
• rename arquillian.xml configuration ajocado to graphene
• note: packages are not renamed
