Should list bots output yaml?

The documentation says:

You can use the output of ``intelmqctl --type json list bots`` to write the ``runtime.conf``

One the one hand intelmqctl --type json list bots is not indented, thus not really usable for humans. On the other hand we are now using yaml. Should list bots get a --yaml switch?

The documentation says:

You can use the output of ``intelmqctl --type json list bots`` to write the ``runtime.conf``

That was actually only true partially, as the user still needed to extract the relevant parts from the huge JSON-structure. And I see no real purpose in doing so unless we have a good and complete workflow which actually helps user in configuring bots using cli-tools only (that would also require to show get individual bot-configuration templates, not all available ones in a row etc.)

So, I propose to remove that line.
