Use pseudo time for junits

Modified feature-active-standby-management and feature-lifecycle
to be able to use TestTimeMulti, eliminating the need for sleep()
calls in the junit tests and speeding the tests up significantly.
Also modified feature-active-standby-management to use a memory DB
for its junit tests.
