[FLINK-7909] Unify Flink test bases
## What is the purpose of the change
Introduce a MiniClusterResource which is used by the AbstractTestBase to
start
and shut down a FlinkMiniCluster. Additionally, this resource registers the
proper
Stream- and ExecutionEnvironment which is now the only way for tests to
start
jobs. This change will thus allow to centrally control which FlinkCluster
will
be started for all test bases.
The AbstractTestBase fully subsumes the functionality of the
StreamingMultipleProgramsTestBase since it now is the most general test base
for streaming and batch jobs. As a consequence, we can safely remove the
StreamingMultipleProgramsTestBase and let all corresponding tests extend
from
AbstractTestBase.
## Brief change log
- Introduce `MiniClusterResource` which starts a `FlinkMiniCluster` and
registers a `TestEnvironment` and a `TestStreamEnvironment`
- Add `MiniClusterResource` as a `ClassRule` to `AbstractTestBase`
- Remove `StreamingMultipleProgramsTestBase`
