Release 4.6.5

• Rework soft-reboot support introduced in 4.6.0:
  • On transactional systems with systemd 254 the system could hang with with a soft-reboot, as /var and /etc have to be mounted in /run/nextroot explicitly. As a soft-reboot can also be triggered by an admin the mounting of the corresponding mount points was moved to a systemd service to be independent of t-u itself.
  • Support for systemd 255
  • Don't decrease reboot level on multiple commands
  • Various other bugfixes
  • soft-reboot support is disabled by default now to gather more feedback
• libtukit: Fix kexec reboot method to boot kernel / initrd of next snapshot
• tukit: Don't clone lock file handle on exec [boo#1222411]
• t-u: Always use zypper of installed system [bsc#1221346]
• t-u: Remove remaining telemetrics references
