CJ 25ee3f0033 Remove extra s from --add-host
linting...
six.string_types
list-of-strings in examples
disallow extra_hosts support for list-of-dicts
A more thorough sets of tests for extra_hosts
Provide better examples
As per @aanand's [comment](https://github.com/docker/compose/pull/1158/files#r28326312)

  I think it'd be better to check `if not isinstance(extra_hosts_line,
  six.string_types)` and raise an error saying `extra_hosts_config must be
  either a list of strings or a string->string mapping`. We shouldn't need
  to do anything special with the list-of-dicts case.
order result to work with assert
use set() instead of sort()
