[pve-devel] [PATCH v3 manager 2/2] ui: ceph status: add tooltip with details to warnings

[Aaron Lauterer]

This is another step to make it easier for admins to discover more
information for a warning or problem that is shown in the Ceph health
panel.

The length is limited to give a first glimpse. For the full details one
can click on the info/detail button.

changes since
v2:
* don't use arrow functions -> rework context in many places. mainly use
  'this' now
* destroy tooltip when no detail text is present. This can easily be
  tested by setting 'ceph osd set noout' for example
* guard show/hide on info button with '?'

v1:
* only destroy it when leaving the whole grid, use show/hide for all
other situations
* factor out text handling of newlines and max lines
* factor out updating and destroying into their own functions
* add more listeners
* hide it when hovering the info button
* auto update it whenever the store is updated to either hide it
  (nothing under the mouse) or set the content
