Request: Display ownership and group

[nsc-jens]

We are trying to set up dcache-view as a general file access method for Swestore. There are a few things in the web GUI that we miss.

In the interface, show the owner on the file and the group. Preferably with name.

Example:

Type   Name       Owner   Group   Creation time           File location   Size
ICON   beer.jpg   jens    ops     11/7/2019, 3:29:24 PM   Disk            86.1 KB
ICON   food.jpg   2344    ops     11/7/2019, 3:29:32 PM   Disk            92.1 KB

or possibly jens(17003) and ops(2300).

I took a quick look at this, but it doesn't look like the owner/group information is readily available at that stage.

Owner/group shows if you do show detail on an item, but that seems to trigger a full metadata query to get that info. I wasn't able to follow if that's just internal data mangling in dCacheView or if it actually produces extra request(s) to dCache which would make this unfeasible performance-wise to do in a standard file listing.

Actually, since the iron-list only renders what's visible it should be doable even if it produces extra requests. I'll see if I can gather the courage to untangle the web of callbacks needed to make that happen, the current code should have some examples of it.
