Without this patch one can not specify package resource specific
parameters. All the ensure_packages() function does it makes sure
the named packages are installed. This patch allows one to pass
default as a second argument and allow greater flexibility on
packages installations.
Use case like the following are now possible :
* ensure_packages(['r10k', 'serverspec'], {'provider' => 'gem'})
* ensure_packages(['ntp'], {'require' => 'Exec[foobar]'})
