[REEF-1527] Refactor RuntimeClock and implement graceful shutdown correctly.

 * Refactor RuntimeClock for readability and add more Javadoc comments;
 * Fix the bug in RuntimeClock.close() that clears all scheduled events without
   processing them;
 * Clean up and refactor code for Time and derived classes, add Javadocs;
 * Improve logging in RuntimeClock and around;
 * Cosmetic refactoring of RuntimeClock unit tests (new unit tests will be in a
   separate pull request)
 * Avoid loops over entire schedule in .close() and .isIdle() methods to find
   client alarms.
