Add a Deltalake connector

[malonsocasas]

Issue #310 :

Description of changes:
Add a first version of a Deltalake connector (https://github.com/delta-io/delta) so that Athena can interpret table schemas/partitions automatically (some current limitations are listed in the README).

Note that my first attempt was to use: https://github.com/delta-io/connectors. However, the library being in Scala and depending on a lot of packages, it makes it unsuitable for a Lambda code (with a limitation of 250 MB).

Hey @avirtuos I'm following along as well to see if this PR can be merged; it's listed on https://delta.io/integrations as a "preview" release but it would be great if this were an official part of awslabs/aws-athena-query-federation.
