Added support for install_options argument.

install_options can now be specified to allow additional arguments to be passed to the PowerShell Install-Module command, e.g.

    package { 'foobarmodule':
        ensure => latest,
        provider => 'windowspowershell',
        source => 'PSGallery',
        install_options => [ '-AllowClobber' ]
    }
