Importing tpch/ds data for tests #2759
Description
Users who come to try the YDB database will immediately ask the question - how fast is the database. Usually, the answer to this is that they suggest trying to run a standard test dataset of the tpch/ds type.
You need to add a point (?) about test data somewhere in the console in a visible place. In this point, you need to somehow select the dataset type (tpch/tpcds) and size (tpch1/tpch10/tpch100/tpch1000/tpcds1/tpcds100), after which the user will need to run SQL commands in three steps:
create the necessary entities in the database
run data import commands
run queries that will run the benchmark
technically, we have ydb cli, in which this can be done. Alternatively, you can send someone to a documentation page somewhere, where it will be described how to use ydb cli to perform all these 3 points
