As a part of branching to stage 0.2.0 release in #266, set version
for continued development on master branch.

* remove unused declared deps in a few places
* lex sort modules in top level pom
* update maven plugin versions.
* no more jar-with-dependencies
* set ycsb-core to provided in bindings
* introduce a bindings-parent pom that sets
** stage dependency copy on building binding
** iff binding has a README.md, build a binding-specific dist artifact
* update distribution assembly to
** properly build after modules
** use per-binding sets of dependencies

closes #250

* Need a SNAPSHOT version because non-SNAPSHOT is reserved for actual releases.
* Increment minor version per pre-1.0 guidelines from the Version Numbers guide

Fixes #236.

Hbase client has a bug to write all values as empty byte arrays in debug
mode. It is caused by an illegal use of ByteIterator. Values returned
from toString() or toArray() should be cached if they are needed later.

* Bumps `hbase.version` to 1.0.0
* Adds a new database, hbase-10, which targets the HBase 1.0 API.

* Time the cleanUp of a DBWrapper
* For HBase this clean up should also be counted as an update.
