debugd: reset unit failed status before restarting

[daniel-weisse]

Context

On debug images, our bootstrapper and upgrade-agent systemd units continuously fail until the binaries are uploaded using cdbg deploy. Once this is done, the debugd issues a systemctl restart command to those units. Under some circumstances, this restart can fall into the timeout period from our units being rate limited in restarting by systemd. We can use systemctl reset-failed to reset the failed counter and by this way bypass the timeout.

See https://bugzilla.redhat.com/show_bug.cgi?id=1016548 for some more details about the issue. See the man page for systemctl reset-failed.

Proposed change(s)

• Run systemctl reset-failed before restarting a unit in debugd
