Optimize source database size

[Woland2k]

Here are techniques used to optimize source database making sure it has a the lowest size and thus will take less time to initialize:

1. vc-empty-db had a 6mb "sys.plan_persist_runtime_stats", probably from the previous db run. In order to remove the data from that table, run the following command:

ALTER DATABASE [vc-empty-db] SET QUERY_STORE CLEAR;

2. Database has a size it occupies on the disk as well as a claimed size. The claimed size is never reduced even when the data is removed. In order to re-claim unused space, the following command needs to be run:

DBCC SHRINKDATABASE (N'vc-empty-db')
