Show pending publication on the version specific view of a package as well

[Christian Ehrhardt ]

The overview of a source is very useful when waiting for an upload to be ready to be used.
Especially when uploading things together people check if the binaries are published.

As you can see on the attachment "launchpad-misspublishinfo-overview.png"
on the top is an explicit warning to make users aware.
And at the bottom is a list per architecture.

The example was from https://launchpad.net/ubuntu/+source/dpdk

Yet if one checks on the version specific page of this at https://launchpad.net/ubuntu/+source/dpdk/16.11-1 it is rather unclear.

On the right one can see the build status.
And he even might be lured into thinking things are published by the source being stated published on the right.
See "launchpad-misspublishinfo-detail.png"

But the only info I find that the binaries are not published is the "emptiness" in the section "Binary packages built by this source".

It would be really nice if the per-version detail view could also get
- the warning header like "Note: Some binary packages for this source are not yet published in the repository."
- and at the bottom at the list of binary packages the list of pending state per architecture as one could see on the overview.
