I noticed that we're using a homegrown package for assertions. The
functions are extremely similar to testify, but with enough slight
differences to be confusing (for example, Equal takes its arguments in a
different order). We already vendor testify, and it's used in a few
places by tests.
I also found some problems with pkg/testutil/assert. For example, the
NotNil function seems to be broken. It checks the argument against
"nil", which only works for an interface. If you pass in a nil map or
slice, the equality check will fail.
In the interest of avoiding NIH, I'm proposing replacing
pkg/testutil/assert with testify. The test code looks almost the same,
but we avoid the confusion of having two similar but slightly different
assertion packages, and having to maintain our own package instead of
using a commonly-used one.
In the process, I found a few places where the tests should halt if an
assertion fails, so I've made those cases (that I noticed) use "require"
instead of "assert", and I've vendored the "require" package from
testify alongside the already-present "assert" package.

If no fields related to an update config or restart policy are
specified, these structs should not be created as part of the service,
to avoid hardcoding the current defaults.

This adds a new parameter insertDefaults to /services/{id}. When this is
set, an empty field (such as UpdateConfig) will be populated with
default values in the API response. Make "service inspect" use this, so
that empty fields do not result in missing information when inspecting a
service.

Refactor container logs system to make communicating log messages
internally much simpler. Move responsibility for marshalling log
messages into the REST server. Support TTY logs. Pave the way for fixing
the ambiguous bytestream format. Pave the way for fixing details.

This parameter controls the order of operations when rolling out an
update task. Either the old task is stopped before starting the new one,
or the new task is started first, and the running tasks will briefly
overlap.
This commit adds Rollout to the API, and --update-order / --rollback-order
flags to the CLI.

Unless we are adding or removing environment variables, their order
shouldn't be changed. This makes it look like the service's TaskSpec has
changed relative to the old version of the service, and containers need
to be redeployed.
The existing code always rebuilds the list of environment variables by
converting them to a map and back, but there's no reason to do this if
no environment variables are being added.

Refactored the API to more easily accept new endpoints. Added REST,
client, and CLI endpoints for getting logs from a specific task. All
that is needed after this commit to enable arbitrary service log
selectors is a REST endpoint and handler.
Task logs can be retrieved by putting in a task ID at the CLI instead of
a service ID.

Change "service create" and "service update" to wait until the creation
or update finishes, when --detach=false is specified. Show progress bars
for the overall operation and for each individual task (when there are a
small enough number of tasks), unless "-q" / "--quiet" is specified.

This change adds the ability to do --tail and --since on docker service

- Align output. Previously, output would end up unaligned because of
longer task names (e.g. web.1 vs web.10)
- Truncate task IDs and add a --no-trunc option
- Added a --no-ids option to remove IDs altogether
- Got rid of the generic ID Resolver as we need more customization.

Server-side rollback can take advantage of the rollback-specific update

go back to a previous version of the spec.

This fix tries to address the issue raised in 25696 where
it was not possible to specify `--stop-signal` for `docker service create`
and `docker service update`, in order to use special signal to stop
the container.
This fix adds `--stop-signal` and update the `StopSignal` in `Config`
through `service create` and `service update`.
Related docs has been updated.
Integration test has been added.
This fix fixes 25696.
