Fix cold reboot on no wake by rtc (BugFix)

[kissiel]

Description

This PR fixes two problems with the cold-reboot job.

1. It introduces a new field reported by the RTC resource job that informs about presence of the wakealarm functionality necessary to boot the machine after it's shutdown (this is what cold-reboot job does).
2. It changes the hard-coded two-minute alarm setting in favor of a variable that can be defined in configs, launcher, or the calling environment. The default behavior stays the sam - 120s. This fixes a problem where on slow devices it took longer to power off the host than what the delay was (inlcuding two sleeps). Now on those devices we can raise make the delay longer.

Documentation

No documentation changes.

Tests

For the problem no 1. I tested the "happy case" only, because I have no access to a device with broken wakealarm.
The second problem I managed to test by adding sleeps before the poweroff call.
