This allows the user to set a logging mode to "blocking" (default), or
"non-blocking", which uses the ring buffer as a proxy to the real log
driver.
This allows a container to never be blocked on stdio at the cost of
dropping log messages.
Introduces 2 new log-opts that works for all drivers, `log-mode` and
`log-size`. `log-mode` takes a value of "blocking", or "non-blocking"
I chose not to implement this as a bool since it is difficult to
determine if the mode was set to false vs just not set... especially
difficult when merging the default daemon config with the container config.
`log-size` takes a size string, e.g. `2MB`, which sets the max size
of the ring buffer. When the max size is reached, it will start
dropping log messages.

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.

This fix tries to address the issue raised in 29972 where
it was not possible to specify `--read-only` for `docker service create`
and `docker service update`, in order to have the container's root file
system to be read only.
This fix adds `--read-only` and update the `ReadonlyRootfs` in `HostConfig`
through `service create` and `service update`.
Related docs has been updated.
Integration test has been added.
This fix fixes 29972.
