Compose currently only supports a single filter options on --filter,
for which reason the --status flag was added, which is more convenient
to use.
However, the `--filter` flag is common among various docker commands, and
it's possible that additional filters get added at some point (which may
be less "commonly" used, and not warrant a dedicated flag).
This PR removes the "deprecated" mention from the flag, to keep consistency
with other commands, but adds documentation to explain how they relate to
eachother.
Also added a short example for the `--format` flag.
