package versions table shows multiple packages from release pocket

[Brian Murray]

The package version table appends, (R), to the package version from the release pocket. However, there can be only one! package version from that pocket. It'd be more useful if an "(O)" or something else was displayed from obsolete package versions.

An example can be found in this bucket and the Xenial column:

The pocket will still be release, so we'd need to check the status to see if it was "Obsolete" or some other status.

This needs to happen in daisy's launchpad.py and in the errors frontend.
