Add bulk insert feature

[dima-altinity]

in case if its required to add/insert hundreds (or even thousands) Parquet files it will be very useful to have ability to get list of Parquet files from input file. Adding "--from-file" argument for INSERT command. Something like this

/ # ice insert poc.dns_mtree_repl_v2_0_test -p --no-copy --force-no-copy --from-file foo.list

cat foo.list

It will be important to return negative exit code if at least one Parquet file was not inserted successfully.

Also thinking about inserting this big list of files in parallel ( make this process multithreaded) but not sure how it will work with " --thread-count=" argument.
