Replace deprecated tenant_id property

The tenant_id property of RestClient in tempest was deprecated in
25.0.0. This replaces the deprecated property by the new project_id
property to avoid the following warning.

WARNING tempest.lib.common.rest_client [-] Deprecated: "tenant_id"
property is deprecated for removal, use "project_id" instead
