RFR: 8176132:-XX:+PrintSharedSpaces should be converted to use Unified Logging.

Please review this change converting +XX:+PrintSharedSpaces to Unified 
Logging, of the form -Xlog:cds=info. The WizardMode and Verbose 
statements correspond to "trace" level logging, according to the 
standard conversions. Additionally, the tag combinations 
"cds+hashtables", "cds+verification", and "cds+vtables=debug" split up 
the output into more manageable/helpful portions.

Bug: https://bugs.openjdk.java.net/browse/JDK-8176132
Open webrev: http://cr.openjdk.java.net/~rprotacio/8176132.00/
And test/lib/jdk/test/lib/cds/CDSTestUtils.java change at the foot of 
this email.

Tested with JPRT.

Thank you!
