This change contains the roles and testing for deploying certificates on hosts using letsencrypt with domain authentication. From a top level, the process is implemented in the roles as follows: 1) letsencrypt-acme-sh-install This role installs the acme.sh tool on hosts in the letsencrypt group, along with a small custom driver script to help parse output that is used by later roles. 2) letsencrypt-request-certs This role runs on each host, and reads a host variable describing the certificates required. It uses the acme.sh tool (via the driver) to request the certificates from letsencrypt. It populates a global Ansible variable with the authentication TXT records required. If the certificate exists on the host and is not within the renewal period, it should do nothing. 3) letsencrypt-install-txt-record This role runs on the adns server. It installs the TXT records generated in step 2 to the acme.opendev.org domain and then refreshes the server. Hosts wanting certificates will have pre-provisioned CNAME records for _acme-challenge.host.opendev.org pointing to acme.opendev.org. 4) letsencrypt-create-certs This role runs on each host, reading the same variable as in step 2. However this time the acme.sh tool is run to authenticate and create the certificates, which should now work correctly via the TXT records from step 3. After this, the host will have the full certificate material. Testing is added via testinfra. For testing purposes requests are made to the staging letsencrypt servers and a self-signed certificate is provisioned in step 4 (as the authentication is not available during CI). We test that the DNS TXT records are created locally on the CI adns server, however. Related-Spec: https://review.openstack.org/587283 Change-Id: I1f66da614751a29cc565b37cdc9ff34d70fdfd3f
