Example code to generate the hash that the API could return:

results = ::Katello::Host::ContentFacet.select(:bootc_booted_image, :bootc_booted_digest, 'COUNT(hosts.id) as host_count').joins(:host).group(:bootc_booted_image, :bootc_booted_digest)
image_mode_map = Hash.new { |h,k| h[k] = [] }
results.each do |host_image|
  image_mode_map[host_image.bootc_booted_image] << { bootc_booted_digest: host_image.bootc_booted_digest, host_count: host_image.host_count.to_i  }
end

The hash looks like:

{"quay.io/centos-bootc/centos-bootc:stream10"=>[{:bootc_booted_digest=>"sha256:3131aff321a3f34abd4ec7b242d80a75de7fbee32693fe4156d6866fdde0e4cd", :host_count=>1}],...}

This json could power a page that lists each image with the varying hashes inside and a host count for each hash inside the image.

For hammer, I'm thinking users could use a new `hammer host bootc-images` command. It would be a bit similar to the `hammer host facts` paradigm in that it lists aggregate information about all hosts.
