This patch is part of inspector HA work, which wraps inspector api into
oslo service.
oslo.service has also provided support to signal processing like SIGHUP or
SIGTERM, so these code were removed in this patch.
Deprecated current SSL cert/key options used by ironic-inspector, code
manually creates ssl context were removed. These options will be fed
from [ssl] section.
