The test creates an empty space with 1000 nullable columns storing uint64
values. Then it initializes a datasets that consists of 10 columns and
1 million rows (row count and both column counts are configurable), then
it inserts the dataset into the space.

By default the test uses serial C API but one may switch to the Arrow API
for batch insertion (the feature is exclusive to the Enterprise Edition).

It's also possible to specify the engine and wal_mode to use (default are
memtx, write).

Needed for tarantool/tarantool-ee#712
