Fix ssl & docker cert alarms

When ssl & docker_registry certificate expiry alarms were
expected, they were being suppressed due to unknown UUID.
Found the issue to be in the parser of REST response which
should use different keys for ssl/docker_registry and for
ssl_ca certificate types.

Test Plan:
PASS: Alarms are now raised as expected for ssl & docker
      certificate types
