Add dependency on org.eclipse.platform - fix for tests on mac

Ever since we switched to luna, all integration tests stopped working
on mac (all tests using parent pom are affected, not RedDeer).
The Preferences window could not be opened. To fix this,
we add explicit dependency on org.eclipse.platform.feature.group
to all tests.
ServerRequirementConfig supports remote server configuration. No UI interactions implemented.
