[stable-2.7] Reboot - Fix command not found, add Apline support, fix Solaris command (#49272)

* Fix various bugs related in reboot - Use format strings for consistency and improve debug log messages - Use local variables instead of class attributes in order to be thread safe - Run setup module to get distribution and version - Run find module to get full path of shutdown command - Use ansible_os_family and ansible_distribution to find commands and args - Use same command for all Solaris/SunOS distributions - Move delay calculations to properties - Reliably check for module run failure - Fix bug in run_test_command() that accidentally made the method work properly - Use better exceptions rather than Exception - Use dict literals rather than constructors - Correct _check_delay() so it always returns a value, not None - Don't store and return result in run_test_command() because it's not used anywhere - add test for post reboot command that fails - test negative values for delay parameters. (cherry picked from commit c1589c33c4) Co-authored-by: Sam Doran <sdoran@redhat.com>

+bugfixes:
+  - reboot - search common paths for the shutdown command and use the full path to the binary rather than depending on the PATH of the remote system (https://github.com/ansible/ansible/issues/47131)
+  - reboot - gather distribution information in order to support Alpine and other distributions (https://github.com/ansible/ansible/issues/46723)
+  - reboot - use a common set of commands for older and newer Solaris and SunOS variants (https://github.com/ansible/ansible/pull/48986)
