Yong Tang 7fa8d5e064 Add `truncate` function for Go templates
This fix is part of the discussion in 28199 about using
`truncate` to replace `--no-trunc`.

As part of the fix, a new function `truncate` has been
added for Go templates so that it is possible to use
```
docker stack services --format "{{truncate .ID 5}}: {{.Mode}} {{.Replicas}}"
```
to show truncated ID.

A unit test has been added.

This fix is related to 28199.
