OSC future (formerly [glance] Different checksum between CLI and curl)

Erno and I have had this discussion in the hallway at the PTGs before,
so my response should be no surprise.

The Octavia client is exclusively an OpenStack Client (OSC) plugin.
This is partly because python-neutronclient (octavia was a neutron
sub-project at the time) was already deprecated, but also because we
saw the advantages and much improved user experience with OSC.
We also exclusively use OSC for our devstack plugin scripts, etc. This
includes interacting with glance[1].

Personally I have also moved to exclusively using OSC for my
development work. I load/delete/show/tag images in glance on a daily
basis. From my perspective, the basic features of glance work well, if
not better due to the standardized output filtering/formatting

So, I am an advocate for the OpenStack Client work and have
contributed to it[2].

I also understand that glance has some development resource
constraints. So, I have a few questions for the glance team:
1. Do we have RFEs for the feature gaps between the python-glanceclient and OSC?
2. Do we have a worklist that prioritizes these RFEs in order of use?
3. Do we have open stories for any OSC issues that may impact the above RFEs?

If so, can you reply to this list with those links?

I think there are folks here offering to help or enlist help to
resolve these issues.

Is it possible that the unified client will be deprecated in favor of individual clients after more discussion? I haven’t looked at any of the individual clients since 2018 (except for osc-placement which is kind of a special case), because I thought they were all going away and could be safely ignored until they did, and I haven’t included any information about the individual clients in the documentation that I write for our users, and if they ask I have been telling them to not use the individual clients. Do I need to start looking at individual clients again, and telling our users to use them in some cases?

I would ask everyone involved to remember that we operators are down here, and the yellow rain falling on our heads does not smell very good.
