Anchor the consul install/config/run_service classes

[koendc]

This fixes dependency issues on underlying packages and services.

For me this helped to solve a dependency issue between a yum repo and the consul package. I had to add another anchor around the calling consul class:

yum::repo { 'my-repo': }

anchor {'my_consul_first': }
->
class { '::consul':
    install_method => 'package',
    package_ensure => '0.5.0-2.el6',
    require        => Yum::Repo['my-repo'],
}
->
anchor {'my_consul_last': }
