docs: add filter scope for command events and more cluster events

[allencloud]

Signed-off-by: allencloud allen.sun@daocloud.io

This PR adds filter scope for command events, while I think there are still some cluster events missing which are introduced in PR moby/moby#32421.

- What I did

1. docs: add filter scope for command events, covers one part of missing documentation for swarm events #252;
2. add more cluster events service, node, secret, config, and remove in network;
3. add examples;
4. sort some event actions in lexicographical order.

- How I did it

- How to verify it

- Description for the changelog

- A picture of a cute animal (not mandatory but encouraged)

@vieux I updates this PR to add more details in docker events. And these things are described in the PR description. PTAL. Thanks a lot.

ping @vieux @dnephin @thaJeztah
Could you help to review the content added to the docs about events command? ☀️

[thaJeztah]

One nit, but LGTM otherwise

We may want to start thinking if we can present these in a different way, was thinking of a "matrix", but there's a lot of object types that don't share the same event-types, so possibly not a solution

Can you use a capital S here?

Oh, my bad. Updated now. Thanks for the review. ☀️
