when run command "kolla-ansible -i multinode certificates",
the certificates file will generated in all nodes, it is
unnecessary, this ps to make it in deploy node.

Working towards the blueprint that will add TLS protection
for the external endpoints, kolla needs certificates.
When kolla deploys OpenStack, the external VIP will need
a server side certifcate. Clients that access those endpoints will
need the public CA certificate that signed that certificate.
This ansible script will create these two certificates to make
it easy to use TLS in a test environment. The generated
certificate files are:
/etc/kolla/certificates/haproxy.pem (server side certificate)
/etc/kolla/certificates/haproxy-ca.pem (CA certificate)
The generated certificates are not suitable for use in a
production environment, but will be useful for testing and
verifying operations.
Partially-implements: blueprint ssl-kolla
