Aleksei Sviridkin c2c50b4119 test(e2e): give tenant workers CPU headroom above their vCPU count ...

Workers that fail to join have been measured burning their vCPU threads
flat out under a ceiling equal to their vCPU count while the guest
kernel recorded no progress at all, with the emulator, IO, vhost and
vnc threads flat at zero. That is the shape of a vCPU spinning on a
lock whose holder is the other vCPU, preempted out of the quota the two
share, and it predicts that a ceiling with room above the vCPU count
lets the preempted one back in.

What the next runs answer is whether the join failure rate moves. If it
does not, the lever is elsewhere and the value goes back.
