Swap command descriptions and summaries

[msabramo]

Because commander shows the summary when you do aptly-cli --help and
it displays the description when you do - e.g.: aptly-cli repo_upload --help.

So the summary should be shorter than the description.

Before:

just remove last part (POST /api/publish/:prefix/<:repos>or<:snapshots>
