Add version upgrade tests

We have no upgrade tests now. Without them, it's hard to make sure we are not making any unintentional on-disk format changes or behavior changes. This should be a bit...

Store numeric field names as string keys, instead of integers

Document Layer is storing numeric field names as binary integers, this is limiting numeric field names to be an integer. I am guessing this decision is taken to maintain the...

In the **[Connecting to the Document Layer](https://foundationdb.github.io/fdb-document-layer/getting-started-mac.html#connecting-to-the-document-layer)** section, the extension for the _configuration file_ is `.md` instead of `.html`. Same goes for the [Getting Started on Linux](https://foundationdb.github.io/fdb-document-layer/configuration.md) one.

None values are currently not being generated by the random generator in correctness due to #135. We need to reenable it after the issue got fixed.

Because of the problems described in #123, tests(data consistency check between DocLayer and MM) for failure cases when doing `update` tests are disabled. We need to re-enable them for better...

We have functional tests for deletes. And some basic deletes are done part of deterministic correctness. We should add delete tests with randomized queries there.
