Get OSX installation working for realz

Previously we were using the passed in version for the versions of puppet
and its dependencies. This adds :facter_version and a :hiera_version keys
so that we can install those dependencies explicitly on platforms that we
must. It also adds the `-pkg` opt to the installer command to work on
newer OSXs.

Provide default gem installation

This allows the `install_puppet` command to accept an additional parameter
`:default_action` which, if set to 'gem_install' will attempt to install
puppet from gem if it cannot otherwise install puppet. The default for
:default_action is still to fail hard.
Use specified versions if possible

Previously we allowed passing :version, :facter_version, and/or
:hiera_version to `install_puppet` but only respected `:version` with
windows and osx, and the others only on osx. This will attempt to
install the versions specified for any package specified. The version
information is still optional on linux machines, and there is no way for
us to respect the dependency versions on windows (since our windows
package is an omnibus package).

This fixes small bugs within the install_puppet method
Fixup windows support for FOSS

Previously the PATH for windows was only being set to include executables
from git repos, not executables installed from native packages. This
includes the default installation path for native windows packages in the
FOSS command creation.
(QENG-597) 'master' DSL helper can return a non-master node...

...when actual master is confined away

- change around the logic so that the default node is defined at options
  parsing, not during test runtime
- determine the default node by it either being
  1.  the node with the role defined  as 'default'
  2.  the master node
  3.  the only node
  Then add the role 'default' to that node, if necessary
- differentiate between master and default, no longer allow the default
  to be used as a master if the master is undefined (keep roles clear,
  the master should only be the node defined as master)

Fixed issue with default behavior not picking up type and hosts from rake task
fixup test
add tests for new install_puppet functionality
Refactor `puppet_install`

This changes the `puppet_install` function to be more readable and reduce
code duplication. It does not change any behavior.
(QENG-438) Pass feature flags to all instances of `apply_manifest_on`

Prior to this there was a number of configurable options that would
tweak Puppet's behavior when using apply_manifest_on. However there
was no good way of setting all instances of apply_manifest_on to use
a certain set of flags. e.g. set "future" parser to be true for a specific
run of suite without changing all of the tests to explicitly set the
future parser option on apply_manifest_on. This allows users to set default
flags to be passed to puppet when apply_manifest_on is called in the host
file, or in a pre-test step.

Example Host file:
  HOSTS:
    master:
      roles: [ 'master', 'agent' ]
      default_apply_opts:
        parser: future

Example BeakerRSpec spec_helper.rb
  hosts.each do |host|
    host[:default_apply_opts] ||= {}
    host[:default_apply_opts].merge!( :parser => 'future' ) if ENV['FUTURE_PARSER'] == 'true'
  end
