Add additional SPICE configuration options
Recent changes to OpenStack Compute have added a number of new
configuration options for SPICE VDI consoles. Additionally, it is
not always desirable to enable the HTML5 transcoding proxy for
SPICE consoles in Horizon. This patch adds configuration to
globals.yml for most of these new options. Specifically:
* nova_spice_html5: whether to enable the HTML5 transcoding proxy
or not. Defaults to the previous behaviour of enabling the proxy.
Notably, nova_spice_require_secure is not exposed here as it implies
that qemu is configured to support TLS, and that TLS certificates
have been configured in the nova_libvirt container. These changes
are large, and are included in a separate patch for clarity.
Additionally, OpenStack Compute added these configuration options
in 2023.1, and they are exposed as well:
* nova_spice_image_compression: "auto_glz"
* nova_spice_jpeg_compression: "auto"
* nova_spice_zlib_compression: "auto"
* nova_spice_playback_compression: true
* nova_spice_streaming_mode: "filter"
All configuration options and their various values are documented
by OpenStack Compute in their documentation.
Partial-Bug: #2131793 (spice-direct consoles)
