What I did

This changes the output format of compose top and inlines the service container name into the table.

Previously, compose top had printed something like:

<service name>
UID    PID   ...
root   1     ...

Now, the output looks more like this:

SERVICE   UID    PID   ...
<name>    root   1     ...

This is a first draft. The tests could be a bit more exhaustive (i.e. mocking (api.Service).Top()).

Looking at the test cases now, I also think it should ensure to reorder the CMD column to the end.

LGTM, just a comment regarding service vs container name

I've also taken the opportunity to:

  1. Ensure the CMD column is the right-most one, as this column has likely a very diverse length.
  2. Reduced the padding and minwidth parameters passed to tabwriter, to decrease horizontal space requirements.
  3. Rebase the branch onto main.
