* Rename tenant to project in functional test In particular,
rename "admin_tenant_name" to "admin_project_name" and
rename "tenant_name" to "project_name". These configs have been
renamed in tempest [1], so Magnum needs to adapt the change.
* Temporarily remove "subjectAltName" from CSR config, because
it caused failure of certificate signing, possibly, due to a
bug or imcompatible change in pyOpenSSL 16.0.0.
