quill-cassandra: review streaming source

[lvicentesanchez]

Closes #175.

As Cassandra supports pagination by default, this PR changes the way the Observable is created to avoid synchronous queries to Cassandra when we reach the end of current page.

I have disable the encoding sets tests temporarily as I have found an issue with Cassandra 3.x, the version we are using for our CI. We can either use Cassandra 2.2 for our tests or add the second column of EncodingTestEntity to the primary key.

I have reported the issue to the Cassandra Dev mailing list. This is the repo that reproduces the problem:

I'd prefer any alternative that doesn't require commenting the test.

[lvicentesanchez]

I would rather extend the primary key, and once they address the issue
update the CI file.
