This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @sextonkennedy, @rappoccio, @mandrenguyen, @antoniovilela (and backports should be raised in the release meeting by the corresponding L2)

[makortel]

Since #46756 was merged in 14_2_X (just before branching off 15_0_X or something), this PR needs to be backported to 14_2_X.
