[IMP] sale: Apply discount on all SO lines onchage of first SO line

Purpose fo the task is to Allow changing a discount for the whole SO.

So in this commit, On a quotation, with "discount per line" option
enabled, if the user changes the discount on the first SO line, display
a pop-up requesting if they want to apply the change to all the lines
of the SO.
There is condition to open the confirmation dialog to change on all SO lines:
  1. There should be 3 or more lines in SO
  2. Happens only when changing the discount of the first SO line
  3. The initial discount is the same on all lines
For Ex: Example : a SO with a discount of 10% on all 6 SO lines.
The user clicks the discount field on the first so line, changes to 20%.
A pop-up "apply this discount to all quotation lines"
-> if yes, apply 20% to all SO lines.
