letsencrypt: split staging and self-signed generation

We currently only have letsencrypt_test_only as a single flag that
sets tests to use the letsencrypt staging environment and also
generates a self-signed certificate.

However, for initial testing we actually want to fully generate
certificates on hosts, but using the staging environment (i.e. *not*
generate self-signed certs).  Thus we need to split this option into
two, so the gate tests still use staging+self-signed, but in-progress
production hosts can just using the staging flag.

These variables are split, and graphite01.opendev.org is made to
create staging certificates.

Also remove some debugging that is no longer necessary.
