salt-cloud handling cleanups

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.

Wrong list name in config file

Updated minion and master config files to 2016.11

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

Hack to make rendering work on CentOS 6

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

fixed key reserved for lxc_profile file

fix beacons on dev

Add http proxy support for minion

Fixes jinja in include block

Use a different group name for GID 0 depending on the minion's O/S

fix default dict warning with saltstack dev version

Arch Linux: install pygit2 or libgit2 via pacman instead of source

Alpine Linux: add basic support

Added beacon configuration support

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

Fix pygit2-libgit2 builds on Debian like platforms.

Correction for Fedora packaging.

Have salt-api service watch the master config files

The salt-api service is configured using the master config files but is
not restarted when the master is restarted. We need the salt-api service
to watch the master config files to ensure that any config changes are
picked up.
