[Development] Provisioning error on Ubuntu 18.04 image

[Konstantin Tokarev]

Trying to provision Ubuntu 18.04 image with older commits of qt5 repo on 5.13.2 branch (so that image is not just taken from cache) results in the following reproducible error:

+ sudo apt-get install docker-ce -y
Reading package lists...
Building dependency tree...
Reading state information...
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 docker-ce : Depends: containerd.io (>= 1.2.2-3) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.


It seems like there were no recent docker-related changes in provisioning, so I'm afraid that it affects head of 5.13.2 as well (and maybe other branches), and will break things if cache of VM images is cleared
