added test to the checktree directory upgrade_test/check.exp

available tests:
o back up of configuration
  - the test save the initial configuration - must run as the first one, since
this configuration is used for upgrading the cluster back to the initial state.
o upgrade to the initial state - must run as the last one
o test of the upgrade from the additional cluster to the main testsuite cluster,
if additional configuration is specified (otherwise this test is skipped)
