Changes:
1. mongodb configuration parameter bug (mongodb.url)
2. README file change
3. Some cleanup. Default DB is 'ycsb'

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

MongoDB 3.0 driver.

Created tests for the basic DB operations.

Updated MongoDB Inc. Driver version to 3.0.2.

* 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.

to the 3.0 driver from MongoDB Inc. and updated to the new Document and
fluent APIs.

URI to configure the client. Old properties are deprecated and but will
be added to the URI if present and the URI does not already contain a
value for the setting.

When running workloads that use the "insert" operation, we get a lot of
duplicate key exceptions from the server. Changing to upsert to avoid
these exceptions.

Changed reference to original forked repo which is not maintained to this repo to avoid conflicting instructions.   Might want to do that for top level README as well.

example

No need to call getError on writeResult. any errors for writeConcern level will throw exceptions and be caught in catch block

each test client.

Add a control (via properties) for the number of connections the Mongo
instance will create/use.
