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.

Allows the user to use `pretty` as the format string.
This enables users to put custom format options into their CLI config
just like is supported for `docker ps` and `docker images`
