Add ensure_resources() function

New function "ensure_resources()" to support passing hash as parameter OR from hiera backend

This new function is extension of ensure_resource() which will now support to pass multiple values as hash/array OR from hiera backend variables in title argument with additional parameters needed.

It will
process multiple values for a resource type from the passed argument & pass each entry (type, title, params) to ensure_resource() in required format for further processing.
Now user can have duplicate resource check functionality extended to multiple entries with this new function.

Use:
For multiple resources using
hash:
ensure_resources('user', {'dan' => { gid => 'mygroup', uid =>'600' } ,  'alex' => { gid => 'mygroup' }}, {'ensure' =>'present'})

From Hiera Backend:

userlist:
  dan:
    gid: 'mygroup'

uid: '600'
  alex:
 gid: 'mygroup'

Call:
ensure_resources('user',hiera_hash('userlist'), {'ensure' => 'present'})

ensure_packages()
Modified to also support Hash type argument for packages

This modification will call newly added ensure_resources() for processing Hash as second argument.
The original functionality remains same for Array type arguments.

Use:
hiera:

packagelist:
  ksh:
    ensure: latest
  mlocate: {}
  myrpm:
    provider: rpm
    source: "/tmp/myrpm-1.0.0.x86_64.rpm"
    install_options:
      --prefix:
        /users/home
  openssl:
    provider: rpm
    source: "/tmp/openssl-1.0.1e-42.el7.x86_64.rpm"

Call:
ensure_packages($packagelist)
