[pve-devel] [PATCH v4 manager] ui: ceph: improve discoverability of warning details

[Aaron Lauterer]

by
* replacing the info button with expandable rows that contain the
  details of the warning
* adding two action buttons to copy the summary and details
* making the text selectable

The row expander works like the one in the mail gateway tracking center
-> doubleclick only opens it.

The height of the warning grid is limited to not grow too large.
A Diffstore is used to avoid expanded rows being collapsed on an update.

The rowexpander cannot hide the toggle out of the box. Therefore, if
there is no detailed message for a warning, we show a placeholder text.
We could consider extending it in the future to only show the toggle if
a defined condition is met.

changes since v3:

change the whole approach from tooltips and info window to integrating
it into the grid itself
