Add ceph-s3 test non-voting job

This patch added new non-voting gate job to check the s3api compatibility
via swiftstack/s3compat tool that shows the ratio of compatible S3 APIs
in the gate result for each patch. This is very useful to check the possibility
if the new incoming patch breaks S3 API compatibility unexpectedly.

Originally swift3 has this kind of the gate job but we missed the staff
while migrating from swift3 into swift upstream repo so this is the porting of that.

Note that currently the job is against to only tempauth because we don't have
custom gate jobs using keystone environment other than dsvm.
