Steps to reproduce:
1) Create VM - 2VCPU, 4096 RAM 50HDD, Centos Minimal Install, 3 network interfaces
2) download http://mirror.fuel-infra.org/mos-repos/centos/mos9.0-centos7/os/x86_64/Packages/fuel-release-9.0.0-1.mos6341.noarch.rpm
3) yum install fuel-release
4) yum install fuel-setup
5) bootstrap_admin_node.sh
6) check fuel-services
7) bootstrap 2 slaves
8) create env with controller and compute
9) Deploy changes
10 Verify networks

Expected results:
Deployment successfully finished

Actual result:
 Failed to provision with 404 error

Reproducibility:
100% on KVM, VBOX

Workaround:
Change mos and Auxiliary repos from local to online

Impact:
Separate master node deployment feature
