trusty is reported as unsupported in streams

Streams uses distro-info-data which still contains an EOL date of the 17th which lp:simplestreams uses to determine the value of 'supported' in streams. Adding distro-info package.

Also adding the simplestreams project as our cloud-images streams are generated by that code and 'supported' was added at the request of multipass and is currently defined by the distro-info supported field.

We have locally corrected the date in /usr/share/distro-info/ubuntu.csv and streams are being regenerated, meaning we will have trusty marked as supported until April 25, 2019 if further changes are not made.

Marking fix-released for cloud-images as streams now correctly report trusty as supported. This was through a manual distro-info-data change as noted in comment #3 and other changes in streams and distro-info data are needed.

Next actions:
* distro-info-data needs an update in precise ESM to add the esm-eol column and correct the eol column to show the 25th rather than the 17th
* simplestreams and multipass developers will discuss how to reflect end of regular and esm support for a release and allow launching instances throughout a release's lifecycle.

The requested precise-esm fixes should be there (once it mirrors) with:

distro-info 0.8.2ubuntu1
distro-info-data distro-info-data - 0.8ubuntu0.17

The verification of the Stable Release Update for distro-info-data has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

Marking this as Invalid for simplestreams; the bug here is addressed (AFAIK), and we should track any further discussions separately.
