IntegrityAuditor: remove sleep from junit tests

Modified the code to use a CurrentTime object for its "time" operations
(e.g., sleep(), currentTimeInMillis()). Modified junit tests to replace
the CurrentTime object with TestTime objects so they don't actually
do any sleeping.
Reformat "commit" message.
Remove TODO from junit test.
Init testTime in junit setUp().
Add AuditorTime and test classes.
Change "latch" to "semaphore" in comments.
Change time units in junit test from SECONDS to MILLISECONDS.
Add sleep() method to auditor test class.
Reorder field qualifiers.
Change utils scope to "compile" in pom.
