BSim: Add status subcommand to bsim_ctl

[gemesa]

I added the status subcommand to bsim_ctl because I really miss it. While one can run pg_ctl directly to check the status it is easier to use bsim_ctl instead. I think this is a commonly used feature that others might also find helpful.

PostgreSQL reference is available here.

$ ls ~/git-repos/bsim-db
