Reintroduce DataStore ctor taking explicit min_arrays argument
Lets caller specify a reasonable minimum array count without needing
to create an explicit buffer.
Use explicit `min_arrays=1024` for content node bucket DB `DataStore`.
Reduces default memory footprint of an empty (or sparsely populated)
content node bucket DB with a factor of more than 1200x.
