UPSTREAM: <carry>: Handle service-ca cert availability/rotation

There is problem when the service-ca certificate is not available at pod start.
This is an issue because the SystemCertPool is created from SSL_CERT_DIR,
which may include the empty service-ca. The SystemCertPool is never regenerated
during the lifetime of the program execution, so it will never get updated when
the service-ca is filled. Thus, we need to use --pull-cas-dir to reference the
CAs that we want to use. This will also allow OLMv1 to reload the service-ca
when it is reloaded (after 2 years, mind you). Removing the SSL_CERT_DIR setting,
and adding the --pull-cas-dir flag ought to be equivalent to what we have now
(i.e. SSL_CERT_DIR and no --pull-cas-dir), except that rotation will be handled
better.
