[Suggestion] Ability to keep track of distrobox exports

[dnkmmr69420]

It would be useful if distrobox keeps track of exports. The exports could be listed on a yml file organized by container source, and export type. There could be a distrobox-list-exports command that lists exports organized by container and export type. There should be a way to list exports from a specific container like distrobox-list-exports --container my-container to list exports from a specific container. There could also be a distrobox-list-exports --raw option that lists the exports with no organization (useful for programs like hyfetch or neofetch to show the number of exports in the packages area.) --raw and --container should be able to be used combined to list exports not labeled but only from a specific container. --type flag could be used to list exports of only one export type (has bin and app options)

examples

$ distrobox list-exports

container-name:
    app:
        gimp
        firefox
    bin:
        vim
        micro
        htop
my-container:
    app:
        kitty
    bin:
        btop
        mc

$ distrobox list-exports --raw

gimp
firefox
vim
micro
htop
kitty
btop
mc

$ distrobox list-exports --raw --type bin

vim
micro
htop
btop
mc

$ distrobox list-exports --type bin

container-name:
    bin:
        vim
        micro
        htop
my-container:
    bin:
        btop
        mc
