depot_autopilot.run: max nr of tests per boot

Browse Source 
Some platforms (sel4 imx6/imx7) cannot manage to execute all tests in a single
boot. Thus, we re-boot them periodically after a given maximum number of tests
to avoid that arbitrary tests always fail due to the long uptime and not due to
the tests themselves.

If the maximum number of tests is set to 0, no limit is applied.

Fixes #3411
