* 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

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)

Summary: Add metrics on how many requests are exceptions and what type.
Test Plan: behold unit tests.
Differential Revision: https://reviews.facebook.net/D37167
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.

Issues incorporated and incompatible changes called out on the jira.
* Cleaned up references to HLog
* Deprecates HLogKey but maintains it for compatibility
- Moves all Writeable from WALKey to HLogKey
* Adds utility code to CoprocessorHost to help with evolving Coprocessor APIs
* RSRpcServices roll WAL call now requests the non-meta LogRoller roll all logs
- rolls actually happen asynchronously
- deprecated old api (and noted incompatible behavior change)
- modified api in new Admin interface to reflect lack of return values.
* Moved WAL user facing API to "WAL"
- only 1 sync offered
- WALTrailer removed from API
* make provider used by the WALFactory configurable.
* Move all WAL requests to use opaque ids instead of paths
* WALProvider provides API details for implementers and handles creation of WALs.
* Refactor WALActionsListener to have a basic implementation.
* turn MetricsWAL into a WALActionsListener.
* tests that needs FSHLog implementation details use them directly, others just reference provider + factory
- Some tests moved from Large to Medium based on run time.
* pull out wal disabling into its own no-op class
* update region open to delegate to WALFactory
* update performance test tool to allow for multiple regions
* Removed references to meta-specific wals within wal code
- replaced with generic suffixes
- WALFactory maintains a dedicated WALProvider for meta (and so knows about the distinction)
* maintain backwards compat on HLogPrettyPrinter and mark it deprecated.
- made WALPrettyPrinter IA.Private in favor of `bin/hbase wal`
* move WALUtil stuff that's implementation specific to said implementation
- WALUtil now acts as an integration point between the RegionServer and hte WAL code.

In HBASE-8370 "Report data block cache hit rates apart from aggregate cache hit rates"
discussion highlights small changes in caching percentage can make for large
changes in cache contents; e.g. lots of data blocks may be getting evicited
but because meta blocks -- index and blooms -- are staying in cache with
high hit rates, a large data block eviction may show as a small change in
overall cache percentage (e.g. from 99.99 to 99.11).
Changes the getBlockCacheHitPercent from an int to a double.
Also changes name of the jmx metric blockCountHitPercent to be
blockCacheCountHitPercent instead.
May be incompatible change.
