Extract title/description from the annotations?

[owtaylor]

When we format HTML, we extract a title and description by looking for:

org.opencontainers.image.title
label:org.label-schema.name
label:io.k8s.display-name
label:name
label:Name

org.opencontainers.image.description
label:org.label-schema.description
label:io.k8s.description
label:description
label:Description

in that order. But it's not possible to query on name/description, and any client that retrieves the metadata has to do a similar process. Perhaps we should extract the name, description and include it as extra fields on the image. These could then be full-text indexed and used for free-form searches: dynamic/?q=database or something like that.
