* make sure the test classifications are in test scope for their use in the hadoop-compat modules
* added a test category for 'metrics related' since that's what all these tests are for
* categorized tests as small,metrics
Conflicts:
hbase-hadoop2-compat/src/test/java/org/apache/hadoop/hbase/master/TestMetricsMasterSourceImpl.java
* corrects license/notice for source distribution
* adds inception year to correct copyright in generated NOTICE files for jars
* updates project names in poms to use "Apache HBase" instead of "HBase" so jar NOTICE files will be correct
* uses append-resources to include supplemental info on jars with 3rd party works in source
* adds an hbase specific resource bundle for jars that include 3rd party works for binaries
** uses supplemental-model to fill in license gaps
** uses the above and a shade plugin transformation to build proper files for shaded jars.
** uses the above and the assembly plugin to build the proper files for bin assembly
* adds a NOTICE item for things copied out of Hadoop (TODO legal-discuss)

Adds a number of lifecycle-mapping entries which
prevent errors from showing up in Eclipse on a fresh
import of HBase. For plugins defined in the top-level
pom, the mapping is added there; otherwise, the mapping
is pushed down to the child pom.
