ASTERIXDB-1271: Revisit UUID Implementation

- Updated UUID implementation to eliminate marshalling to/from a pair
  of longs, replacing with byte [].
- Eliminate all but one call to SecureRandom at init time, avoid risk
  of entropy exhaustion
- Fix exceptions thrown
- Incorporate constant to represent number of bytes, String chars in
  an instance of AUUID
- Split generated from parsed AUUID
- Eliminate intermediate StringBuilder construction on priting paths,
  optimize imports

> AUUID contains an implementation of UUIDs. We should be able to either use the one provided by the JDK or to change ours to be optimized towards our use cases (e.g. choosing a byte array oriented representation that enables us to get rid of AMutableUUID).
