Introduce MT index update, allow users to specify the count of threads/silos to use while importing index. Without code change threads = 1 and there is no change in codepath (everything works as before).
This change (ingesting GZIP files raw records into Lucene index on multiple threads) on my PC halves the execution time: while BasicUsageExample on master takes over 15 minutes to finish (when doing full update), this PR makes it under 7 minutes when using 4 threads.
