Feature our cloud donors on opendev.org

Add logos for our cloud donors, similar to the
https://openinfra.dev/members/#infrastructure or
https://www.openstack.org/community/supporting-organizations/#infra-donors
lists.

Companies whose logos are listed on the OpenInfra members page have
given explicit permission to the foundation to display those logos
in order to promote their involvement in foundation-led activities,
which includes projects and communities represented by the
foundation (like the OpenDev Collaboratory). The agreements the
companies referenced in this change have entered into aren't limited
to specific web sites, so displaying them on opendev.org shouldn't
require that we seek additional permission in order to do so.

When adding these logos in a subdirectory (for ease of maintenance),
we need to update the copy step from the assets image to the gitea
image making it recursive, otherwise the directory will be omitted
form the final image build. It's also worth noting that COPY
directives in Dockerfiles behave in an odd and non-shell-like
manner, as they flatten the files when recursing source directories,
so you end up needing to force them into the intended target
directories.
