Add reboot action plugin (#35205)

* Update docs

* Add reboot action plugin

Refactor win_reboot so it is subclassed from reboot

* Use new connection methods

* Test fixes

* Use better uptime command for Linux

Use who -b to get the last time the system was booted rather than uptime, which changes every second.

* Use distribution specefic commands and flags

Query the managed node to determien its distribution, then set the appropriate command and flags.

* Tune debug messages a bit

* Update module docs with details about pre_reboot_delay

s docs

* Ensure that post_reboot_delay is a positive number

* Remove the stringification

* Add integration tests

* Make sure aliases are honored

* Handle systems that have an incorrect last boot time

SystemD and fakehw-clock do not properly set the
last boot time and instead always set it to epoch.
Use a different command if that is the case.

* Copyright and encoding fixes

* Minor fixes based on feedback

* Add exponential backoff to sucess check method

* Update integration test

Skip the integration test if it would try to reboot the control node. We need a new mechanism to account for this scenario in ansible-test, so tests must currently be run manually for this plugin.
