FIX: Crypto execution order

FIX: Crypto execution order

Currently, VAT history looks like this:

sw_interface_set_flags sw_if_index 2 admin-up
sw_interface_set_flags sw_if_index 1 admin-up
sw_interface_dump
sw_interface_set_flags sw_if_index 2 admin-up
sw_interface_set_flags sw_if_index 1 admin-up
sw_interface_add_del_address sw_if_index 2 192.168.10.1/24
sw_interface_add_del_address sw_if_index 1 172.168.1.1/24
ip_neighbor_add_del sw_if_index 2 dst 192.168.10.2 mac 68:05:ca:3a:af:40
ip_neighbor_add_del sw_if_index 1 dst 172.168.1.2 mac 68:05:ca:35:78:e9
ip_add_del_route 10.0.0.0/8 via 192.168.10.2  sw_if_index 2
resolve-attempts 10 count 1
exec exec /tmp/ipsec_create_tunnel_dut1.config

It should be like this:

sw_interface_add_del_address sw_if_index 2 192.168.10.1/24
sw_interface_add_del_address sw_if_index 1 172.168.1.1/24
ip_neighbor_add_del sw_if_index 2 dst 192.168.10.2 mac 68:05:ca:3a:af:40
ip_neighbor_add_del sw_if_index 1 dst 172.168.1.2 mac 68:05:ca:35:78:e9
ip_add_del_route 10.0.0.0/8 via 192.168.10.2  sw_if_index 2
resolve-attempts 10 count 1
exec exec /tmp/ipsec_create_tunnel_dut1.config
sw_interface_set_flags sw_if_index 2 admin-up
sw_interface_set_flags sw_if_index 1 admin-up
