This fix tries to address the issue raised in 29291 where
the output of `--replicas` in `service create/update`:
```
--replicas uint Number of tasks (default none)
```
is misleading. User might incorrectly assume the number of replicas
would be `0` (`none`) by default, while the actual default is `1`.
The issue comes from the fact that some of the default values are
from daemon and it is not possible for client to find out the default
value.
In this case, it might be better to just simply not displaying `(default none)`.
This fix returns "" for `Uint64Opt` so that `(default none)` is hidden.
In addition to `--replicas`, this fix also changes
`--restart-delay`, `--restart-max-attempts`, `--stop-grace-period`,
`--health-interval`, `--health-timeout`, and `--restart-window`
in a similiar fashion.
New Output:
```
--health-interval duration Time between running the check (ns|us|ms|s|m|h)
--health-timeout duration Maximum time to allow one check to run (ns|us|ms|s|m|h)
...
--replicas uint Number of tasks
...
--restart-delay duration Delay between restart attempts (ns|us|ms|s|m|h)
--restart-max-attempts uint Maximum number of restarts before giving up
--restart-window duration Window used to evaluate the restart policy (ns|us|ms|s|m|h)
...
--stop-grace-period duration Time to wait before force killing a container (ns|us|ms|s|m|h)
```
The docs has been updated. Note the docs for help output of `service create/update`
is out of sync with the current master. This fix replace with the update-to-date
help output.
This fix fixes 29291.
