feat(tempest): Add tempest identity compatibility verify test

[gtema]

Add a third skaffold module that runs the tempest identity v3 test
suite against both keystone-rs and keystone-py (already deployed
side by side by the keystone module), packaged as a new
tempest-identity image built from tools/Dockerfile.tempest.

Not every v3 operation is implemented by keystone-rs yet, so this
runs and reports independently of the main verify suite
(skaffold verify -m tempest) and is invoked as a non-blocking,
continue-on-error step in CI. Failing test IDs are printed per
target in the pod logs and, in CI, collected into a job summary and
an uploaded log artifact so compatibility gaps and regressions can
be tracked over time without gating merges.
