Feature: Make wait time for reboot configurable

[Klaas-]

Hi,
currently reboots are announced 10 minutes prior to the actual reboot happening:

LinuxPatchExtension/src/core/src/bootstrap/Constants.py

Line 191 in 3e34573

REBOOT_BUFFER_IN_MINUTES = 15

LinuxPatchExtension/src/core/src/core_logic/RebootManager.py

Line 34 in 3e34573

self.minutes_to_shutdown = str((Constants.REBOOT_BUFFER_IN_MINUTES - 5) if (Constants.REBOOT_BUFFER_IN_MINUTES > 5) else Constants.REBOOT_BUFFER_IN_MINUTES) # give at least 5 minutes for a reboot unless the buffer is configured to be lower than that

I would like reboots to happen immediately, I do not need to warn users, ssh logins are rare on most of the servers I'd like to update. So this may be a good value to give into user control. It will also save a lot of time on the maintenance windows, My maintenance windows are usually 15-20 minutes duration, 10 minutes of that is reboot -- 20 minutes if there was a pending reboot when the maintenance window was started :)

Greetings
Klaas

Thanks for the feedback. We will evaluate the ask against our larger backlog of work.

Reboot notification timeout has been reduced to 3 minutes and a bunch of other improvements have been added.
