Add a sort option to Nova, so that we would --include-all and sort all outdated packages to the start or end

Is your feature request related to a problem? Please describe. When running Nova with --include-all an --format=table the outdated Charts are mixed with non-outdated ones, since the output is sorted by Namespace.

Describe the solution you'd like We would like to be able to sort by the Old field in ASC or DESC order.

Seems like a great idea. Probably need both a --sort-by and a --sort-order or something like that so that we could sort on any column header. We would love to see a pull request from the community on this!
