[pve-devel] [PATCH manager 1/2] ui: resource tree: use 'diskuse' instead of calculating everytime

[Dominik Csapak <d.csapak@proxmox.com>]

the resource store has a field 'diskuse' which it calculates on update.
Use that instead of calculating the value ourselves everytime.

For change detection, we only need a resolution of 0.01 (since we want
to use the percentage as integer) so check that the difference of old and new
is bigger than 0.9% .
