importd: drop dkr support The current code is not compatible with current dkr protocols anyway, and dkr has a different focus ("microservices") than nspawn anyway ("whole machine containers"), hence drop support for it, we cannot reasonably keep this up to date, and it creates the impression we'd actually care for the microservices usecase.

bash-completion: list valid signal names this is a follow-up for commit 18540892d18addc4dcb81

shell-completion: add pseudo machine ".host" to shell completion

shell-completion: add "machinectl shell" to bash completion logic

shell-completion: bash: make list-transfers and cancel-transfer STANDALONE list-transfers and cancel-transfers don't take machine arguments.

shell-completion: bash: add image transfer subcommands

shell-completion: use list-images rather than list "machinectl list" only lists running machines while many of the MACHINES commands use names of images; both running and non-running. List machines from both "list" and "list-images" and use sort -u to avoid duplicates.

shell-completion: update machinectl bash completion Many new subcommands have been added since the bash completion was last updated. Bring it up to speed.
