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.

This fix ignore some functions in the Go template when header is
redendered, so that `--format "{{truncate .ID 1}}"` will still
be able to redener the header correctly.
Additional test cases have been added to the unit test.

This fix is an attempt to address
https://github.com/docker/docker/pull/28213#issuecomment-273840405
Currently when specify table format with table `--format "table {{.ID}}..."`,
the delimiter in the header section of the table is always `"\t"`.
That is actually different from the content of the table as the delimiter
could be anything (or even contatenated with `.`, for example):
```
$ docker service ps web --format 'table {{.Name}}.{{.ID}}' --no-trunc
NAME ID
web.1.inyhxhvjcijl0hdbu8lgrwwh7
\_ web.1.p9m4kx2srjqmfms4igam0uqlb
```
This fix is an attampt to address the skewness of the table when delimiter
is not `"\t"`.
The basic idea is that, when header consists of `table` key, the header section
will be redendered the same way as content section. A map mapping each
placeholder name to the HEADER entry name is used for the context of the header.
Unit tests have been updated and added to cover the changes.
This fix is related to #28313.

For some reason, `go vet` and `go fmt` validate does not capture
several issues.
The following was the output of `go vet`:
```
ubuntu@ubuntu:~/docker$ go vet ./... 2>&1 | grep -v ^vendor | grep -v '^exit status 1$'
cli/command/formatter/container_test.go:393: possible formatting directive in Log call
volume/volume_test.go:257: arg mp.RW for printf verb %s of wrong type: bool
```
The following was the output of `go fmt -s`:
```
ubuntu@ubuntu:~/docker$ gofmt -s -l . | grep -v ^vendor
cli/command/stack/list.go
daemon/commit.go
```
Fixed above issues with `go vet` and `go fmt -s`

Passing {{.Networks}} to the format parameter will prompt ps to
display all the networks the container is connected to.
