TEPHRA-263 Fix test cases and TTL enforcement for tables configured to read
non transactional data.

> TTL is not strictly enforced, if there are long transactions running

> URL: https://issues.apache.org/jira/browse/TEPHRA-263
> Project: Tephra
> Issue Type: Bug
> Reporter: Ali Anwar
> Assignee: Ali Anwar
> Fix For: 0.14.0-incubating

>
> The logic for filtering for TTL:
> https://github.com/apache/incubator-tephra/blob/release/0.12.0-incubating/tephra-core/src/main/java/org/apache/tephra/util/TxUtils.java#L66
> It is subtracting the TTL duration from the visibility upper bound, but it
> should be subtracting from the current time or the current write pointer
> instead. Otherwise, if the TTL is 1 hour, but the visibility upper bound is
> 22 hours ago (due to some MR that has been in progress for 22 hours), then
> the TTL that is actually enforced will be 23 hours and older data will be
> filtered.
> After the long transactions are invalidated, the TTL is then strictly
> enforced.
