Add run-shell-command for Commands (#1682)

* add run_shell_command

* docgen

* fix command name

Co-authored-by: Blaž Hrastnik <blaz@mxxn.io>

* refactored Info::new

* show 'Command failed' if execution fails

* TypedCommand takes care of error handling and printing the error to the statusline.

* docgen

* use Popup instead of autoinfo

* remove to_string in format!

* Revert chage in info.rs

* Show "Command succeed" when success

* Fix info.rs
