Andrey Smirnov afa8a48174 chore: implement reboot test
Reboot test does node-by-node reboots followed by cluster health checks
(same as done by provisioner).

Fixed bug with `Read()` returning `Reader` instead of `ReadCloser`
(minor).

Allowed `bootkube` to be `Skipped` (for rebooted node).

Added support for doing checks via provided client instance.

Implemented generic capabilities to skip tests based on cluster
platform.
