Issue regarding `validate_integer`

My code looks like:

# this may be wrong, can't tell yet!
class {'etcd':
  listen_client_urls    => 'https://0.0.0.0:2379',
  advertise_client_urls => "https://${facts['fqdn']}:2379",
  listen_peer_urls      => 'https://0.0.0.0:2380',
  etcd_name             => 'default',

  client_cert_auth      => true,
  peer_client_cert_auth => true,
  cert_file             => "/etc/pki/simp-testing/pki/bogus_cert",
  key_file              => "/etc/pki/simp-testing/pki/bogus_key",
  trusted_ca_file       => "/etc/pki/simp-testing/pki/bogus_cacert",
  peer_cert_file        => "/etc/pki/simp-testing/pki/bogus_cert",
  peer_key_file         => "/etc/pki/simp-testing/pki/private/bogus_key",
  peer_trusted_ca_file  => "/etc/pki/simp-testing/pki/bogus_cacert",

  initial_advertise_peer_urls => "https://${facts['fqdn']}:2380",
  initial_cluster             => [ 'master01=https://master01:2380' ],
}

And when I run it I get:

Error: Evaluation Error: Error while evaluating a Function Call, '[[10000, 100, 1000, 0, 5, 5, 5000, 30000, 1000, 5000, 0]]' is not an integer. at /etc/puppetlabs/code/environments/production/modules/etcd/manifests/init.pp:309:3 on node node.domain

which is making absolutely no sense to me. It seems to be turning the array of integers into an array of an array. I'm not modifying these parameters at all, and the module works fine when I comment out the validate statement.

Would you be interested in a PR to validate each int individually or switch to data types?
