Support Openstack Swift object store

[airbots]

Openstack Swift is also widely used object store. Many vendors like rackspace, Oracle, etc. It will be nice to support Openstack Swift as well.

Hi @airbots Do you have your own deployment of Swift ? if hadoop file system for swift is stable, it will be easy to make it work with StreamX - do you have any experience with that ?

Yes, I create cloudstream (similar changes as streamx did for s3 based on hdfs connector) for kafka to access swift object store. It is in my github repository.
