Use CONF.identity.disable_ssl_certificate_validation in object_client

create_object_continue interface in object_client doesn't use
CONF.identity.disable_ssl_certificate_validation, so even if we set
disable_ssl_certificate_validation=true in tempest.conf, sometimes
we will still get "ssl.SSLCertVerificationError:
[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed:
unable to get local issuer certificate (_ssl.c:1108)"

So create_object_continue should judge whether to check ssl
certification according to
CONF.identity.disable_ssl_certificate_validation.
