Autocomplete works only for specific zypper commands like "zypper install" or
"zypper info". It's probably not implemented but it would be very helpful if
package name autocomplete would work for other commands like "zypper addlock".
Since some zypper commands already have autocomplete for further command
options (for example "zypper addlock --type") there would be a need to start
autocomplete for package names only when a character different from dash/minus
(--) is entered.

workflow example: I want to lock a specific Intel package, but I'm unsure about
the right package name
1. type "sudo zypper addlock intel"
2. double tap TAB
3. autocomplete suggest "intel-cmt-cat intel-gpu-tools intelhex intel-SINIT"
