--- deprecations: - As mentioned in the release notes of the Mitaka release (version 13.0.0), the EC2API support was fully removed. The *s3* image service related config options were still there but weren't used anywhere in the code since Mitaka. These are now deprecated and may be removed as early as the 15.0.0 release. This affects ``image_decryption_dir``, ``s3_host``, ``s3_port``, ``s3_access_key``, ``s3_secret_key``, ``s3_use_ssl``, ``s3_affix_tenant``.
