Not generate config file in /etc/nginx/sites-available

[huzhennan]

example code
`include nginx

nginx::resource::location { 'www.test.com-alias':
ensure => present,
location => '/some/url',
location_alias => '/new/url/',
server => 'www.test.com',
}
`

create location nginx config, config file not generate.

in manifests/resource/location.pp use puppetlabs-concat generate config file,
before use concat::fragment need invoke
concat {$config_file: ensure => present, }
