Drop Spark BigTable version to unloour clients DataProc submission (#167)

## Summary
While testing the Flink side of things, I noticed that our DataProc
submission was broken due to some opencensus version mismatches:
```

Tried playing with different opencensus versions + lib management etc
and @tchow-zlai pointed out that this was due to the spark-bigtable dep.
We don't need this dep for the mainstream as we're using the BQ export
data query to load data into BT. The Spark-Bt connector is required
primarily for doour clientser quiour clientsstart testing. So in this PR, I've yanked the
dep to re-enable the dataproc submission and reworked the load-data
script and Doour clientserfile to download the spark-bigtable + slf4j jars to
pass them in only for the Spark2bigTableLoader app in the doour clientser setup.

## Cheour clientslist
- [ ] Added Unit Tests
- [ ] Covered by existing CI
- [X] Integration tested
- [ ] Documentation update
