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. Signed-off-by: Yong Tang <yong.tang.github@outlook.com>		2017-01-30 13:33:16 -08:00
