model-config image-stream not applying to model machine instances

[Ryan Beisner]

I've just noticed that I'm getting 'released' images for my model instances, despite setting image-stream to daily. The controller instances, however, do use a daily image as expected. This is Juju 2.1.2 + OpenStack Provider against an Ocata undercloud.

#### On a user's model, the instance is based on the *release* image, when the *daily* image was expected.

For reference - same issue as bug 1672879
For agents, it can be argued that the controller agent stream should override model streams for API compatibility reasons. For image streams, that assertion doesn't hold true.

[Tim Penhey (thumper)]

Ryan, we can prioritise this and other stakeholder issues based on how much they really hurt us.

[Anastasia (anastasia-macmood)]

Similar behavior has been observed with image-metadata-url as per bug # 1836814. Since both properties are in the same area, potentially these 2 bugs can be fixed at the same time.
