Dynamo DB support
This PR adds Amazon DynamoDB support to MetaModel. A few notes on the
implementation:
* I'm personally fairly happy with the read/discovery/query part of
things. As much as possible is leveraged from Amazon's SDK, but since DynamoDB
is essentially schemaless, there's also the usual option of supplying
`SimpleTableDef` objects.
* Creating tables is a bit funky. There are options in creating a DynamoDB
table that I haven't seen elsewhere, such as the throughput capacity flags. I
added system properties for those. There is also in the SDK options for
creating secondary indices, but I didn't find a good way to map that to
MetaModel during CREATE TABLE. So I left it out.
* The testing is pretty sparse right now, and you need a set of Amazon
credentials to make what is there work. Not sure if there is a mock service
available somehow, or an embedded version of DynamoDB.
