they get overwritten from defaults.yaml if not specified

Changing cmd.wait to cmd.run as recomended on the documentation: https://docs.saltstack.com/en/latest/ref/states/all/salt.states.cmd.html#salt.states.cmd.wait

Proposed pull request for elasticsearch returner in the minion.d/f_defaults.conf file

I use Salt environments to provide each of my team mates the ability to develop
and test their Salt changes. And I've found that when we run this formula from
our environments against our salt-master, comments in some files change. For us
this represents an unwanted and unplanned change. I understand the intention -
to identify how or why the file changed, but I firmly believe that we should
be able to run highstsate with test=True and only see intended changes. Here's
an example:

            ID: salt-cloud-providers
      Function: file.recurse
          Name: /etc/salt/cloud.providers.d
        Result: None
       Comment: #### /etc/salt/cloud.providers.d/saltify.conf ####
                The file /etc/salt/cloud.providers.d/saltify.conf is set to be changed

add missing comas

SaltStack provides "versioned" repositories, this commit add a way
to set which release of salt to use.
It adds a pillar "salt:release" which can be set to a specific release
(ex: 2016.11). This release is then used to configure properly the
repositories URLs for Debian/Ubuntu/RedHat.
The default behavior is to point to 'latest', retaining the previous
behavior if the "salt:release" pillar is not set.

This now properly also supports per user, per minion as well as
function argument limiting.

As discussed in PR#305, these are defaults that even if they are
configurable as probably not suited to a majority of users and causes
delete/add output on highstate of user of the formula choses to use
the same file name.

Since the set of directories is known, just iterate of its well known
names directly. Make sure files are dumped after `file.recurse` to avoid
deletion/creation cycles when applying highstate.

Also apply permissions on cloud.providers.d after all creations steps
are done.

Added parameters new to 2016.03 (or simply missing in the existing config).

pillar (backwards compatibility)

Checks for 'dict' in `x.__class__.__name__` b/c
neither `type()` nor `isinstance()` is available.

!!   Not tested with an actual   !!
 !!  configured `ext_pillar` yet  !!

- jinja on RHEL/CentOS 6 has no 'mapping'
  test (see salt-formula issue #193)
- {% do ... %} allows no assignment, only
  function calls
- of course, `type(foo) is dict` doesn't
  work because it's no jinja test
- maybe `.isinstance()` would be nicer/more
  reliable

Some Unix variants name GID 0 "wheel".  Unfortunately, one cannot
specify this group by ID, because Python conflates integer 0 with
boolean False, nor can one specify this group using the string '0',
because of assumptions in the Salt or Python codebases regarding group
names.

Some vars were missing {{ }}
Indentation was broken
isinstance is not available in Salt
