Use non-privileged build tool

[kwiatekus]

Description

We are looking for the docker build tool that allows for as little permissions as possible:

• can run in non-privileged container (MUST)
• can run as non-root ( STRETCH)

The most promising are kaniko and makitu.
We need to setup those tools in clusters with non-privileged policy enabled and compare them

Reason

We need to enable non-privileged container policy
It is a follow up for #9976
