Prepares the test environment for the test run.

For example, installs software, tweaks env settings for testing, launches targets etc.

Note that multiple ITargetPreparers can be specified in a configuration. It is recommended that each ITargetPreparer clearly document its expected environment pre-setup and post-setUp. e.g. a ITargetPreparer that configures a device for testing must be run after the ITargetPreparer that installs software.
