Bug Description



relying on `random.randrange` when selecting IP from subnet `allocation_pool`.

It cause some problems with Contrail SDN. For internal usage, Contrail allocates `:1` and `:2` (as well as `.1` and `.2`), where `:1` acts as a gateway and `:2` acts as a DNS.

Since tests aren't expect anything on `:2`, when by pure random this IP got selected for test purpose - test fails.

tempest.lib.exceptions.Conflict: Conflict with state of target resource

The extra confusion here adds by the fact that test_dhcp_stateful_fixedips_duplicate actually tests conflict situation.
