@darshan-sj As we spoke earlier, here's the first patch for PropertyGraph support in import/export. I will send the subsequent as I get them completed.

@asthamohta @shreyakhajanchi An fyi, you were auto-selected for review. I've been in conversation with @darshan-sj regarding this effort. But I don't seem to have the permissions to change the reviewer to him.

The build should be fixed now. Turned out to be a dependency issue as OpenJDK 11 doesn't come with javaFX anymore (which Pair depends on). I updated and removed it.

Applied mvn spotless. I don't seem to have the permissions to add the label. But I believe the label should be "improvement" for this.

@darshan-sj Added Graph INFORMATION SCHEMA patch which populates Ddl.PropertyGraph by parsing information schema. One more patch pending for Import/ExportTransform, which I will push shortly.

@darshan-sj I've pushed the code for import/export of graphs as well. I tested it and was able to export a graph from one DB and import it into another. I also tried exporting multiple graphs at the same time and it works.

As mentioned in our other chat, the only remaining issue is that the ImportFromAvroTest for graph fails with a cryptic error inside Beam, so I've commented it out for now, but will reenable it once we get to the bottom of that issue.

For all other purposes, DataflowTemplates for graph works well.

The IT failure is not related to the code changes in this PR.
