Update octavia regexes

Update octavia regexes

It stops using noop drivers and adds all scenarios except:
 - .*api.v2.test_availability_zone
 - .*api.v2.test_availability_zone_profile
 - .*api.v2.test_member.MemberAPITest.test_member_ipv4_create
 - .*api.v2.test_member.MemberAPITest.test_member_ipv6_create

It doesn't run ipv6 which asks for a deep dive (ipv6 from containers?)
It increases threads to 3 as the other testcases.
