Add `--filter enabled=true` for `docker plugin ls`

This fix adds `--filter enabled=true` to `docker plugin ls`,
as was specified in 28624.

The related API and docs has been updated.

An integration test has been added.

This fix fixes 28624.

## Filtering
The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
The currently supported filters are:
* enabled (boolean - true or false, 0 or 1)
### enabled
The `enabled` filter matches on plugins enabled or disabled.
