SPARK-14679: Fix UI DAG visualization OOM.
## What changes were proposed in this pull request?
The DAG visualization can cause an OOM when generating the DOT file.
This happens because clusters are not correctly deduped by a contains
check because they use the default equals implementation. This adds a
working equals implementation.
## How was this patch tested?
This adds a test suite that checks the new equals implementation.
