Move server configs outside A2OA folder

This is to prevent config.cfg, BEServer.cfg and HiveExt.ini passwords
being read by in-game scripts. Also consolidated to a single folder so
we only need to maintain one copy of BattlEye filters, HiveExt.ini,
basic.cfg and server.Arma2OAProfile. These files are identical for all
maps.

Updated rotate_logs.bat with missing files
