The integration tests have long been painful to maintain with settings in various places and copied to multiple types, inconsistent variable names, and otherwise difficult to maintain code. Now the settings for a test suite are all in one place and they remain in the same settings type throughout the test. The multi-cluster suite is also refactored to use the same install and uninstall helpers as the other suites. Signed-off-by: Travis Nielsen <tnielsen@redhat.com>
