Split "name" of test tool to "component" and "artifact"

Split "name" of test tool to "component" and "artifact"

The "name" of the test tool was an ad-hoc specification of
the test tool that the deployment framework was needed to
somehow use to locate the artifact in Nexus. After reviewing
the code that searches for the artifact I decided to separate
the "component" and the "artifact" into their own arguments
to make this distinction explicit. This is also necessary
to support the increasing complexity of the artifact search.
