IMPALA-11306: Create symlink for dataset of scale factor 1
single_node_perf_run.py and load-data.py can fail if user set scale
factor argument 1. This is because generate-schema-statements.py will
insert the scale factor into the database name (ie., "tpch1"), but the
preload script omit the scale factor when creating dataset
directory (ie., "tpch"). This patch fix the issue by additionally
creating symlink for scale factor 1.
Testing:
- Manual test by running the following script:
./bin/load-data.py --scale_factor=1 --workloads=targeted-perf \
--table_formats=text/none/none

> single_node_perf_run.py has a required argument "scale". If scale > 1, the
> script runs fine. But if scale = 1 and load is true, the data loading script
> will fail due to missing dataset. This is becasue the preload script omit the
> scale number padding when creating dataset directory.

> ie., tpch scale 1 will create dataset dir "testdata/impala-data/tpch".
> On the other hand, generate-schema-statements.py will create template sql
> referring to "testdata/impala-data/tpch1".

> Consider creating symlink if scale factor = 1 in the preload script.
