[FLINK-6867] [elasticsearch] Fix instable Elasticsearch 1.x ITCases
The root cause for the instability in ES 1.x is that we're testing both
embedded client mode and transport client mode against the same Elasticsearch
environment. This PR ignores the embedded mode testing, as that method is
generally discouraged anyways.

> Elasticsearch 1.x ITCase still instable due to embedded node instability

> Key: FLINK-6867
> URL: https://issues.apache.org/jira/browse/FLINK-6867
> Project: Flink
> Issue Type: Bug
> Components: ElasticSearch Connector, Tests
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Tzu-Li (Gordon) Tai
>
> The integration tests for Elasticsearch 1.x seems to still be instable, being
> that the test is failing more frequently recently. One example is [1].
> The last attempt to fix this was FLINK-5772, in which the test attempts was
> increased to 3. This doesn't seem to fix the issue. In the worst scenario,
> since the root cause is an instability with Elasticsearch 1.x's embedded
> node, and ES 1.x is a very old version that is usually recommended to be
> upgraded from, we could also consider removing the IT test for ES 1.x.
