Ian Wienand c9215801f0 Generate ssl check list directly from letsencrypt variables
This autogenerates the list of ssl domains for the ssl-cert-check tool
directly from the letsencrypt list.

The first step is the install-certcheck role that replaces the
puppet-ssl_cert_check module that does the same.  The reason for this
is so that during gate testing we can test this on the test
bridge.openstack.org server, and avoid adding another node as a
requirement for this test.

letsencrypt-request-certs is updated to set a fact
letsencrypt_certcheck_domains for each host that is generating a
certificate.  As described in the comments, this defaults to the first
host specified for the certificate and the listening port can be
indicated (if set, this new port value is stripped when generating
certs as is not necessary for certificate generation).

The new letsencrypt-config-certcheck role runs and iterates all
letsencrypt hosts to build the final list of domains that should be
checked.  This is then extended with the
letsencrypt_certcheck_additional_domains value that covers any hosts
using certificates not provisioned by letsencrypt using this
mechanism.

These additional domains are pre-populated from the openstack.org
domains in the extant check file, minus those openstack.org domain
certificates we are generating via letsencrypt (see
letsencrypt-create-certs/handlers/main.yaml).  Additionally, we
update some of the certificate variables in host_vars that are
listening on port !443.

As mentioned, bridge.openstack.org is placed in the new certcheck
group for gate testing, so the tool and config file will be deployed
to it.  For production, cacti is added to the group, which is where
the tool currently runs.  The extant puppet installation is disabled,
pending removal in a follow-on change.

Generate SSL check list

This role automatically generates a list of domains for the certificate validation checks. This ensures our certificates are valid and are being renewed as expected.

This role must run after letsencrypt-request-certs role, as that builds the letsencrypt_certcheck_domains variable for each host and certificate. It must also run on a host that has already run the install-certcheck role.
