[PATCH v3 5/5] auto-t: add test for AddressRandomization option

[James Prestwood <prestwoj@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 6034 bytes --]

Tests all cases of AddressRandomization=network

1. Deterministic generation per-network (default)
2. Full randomization per-network
3. Address override per-network
