Strict typing in Puppet 4 error

[iwalz]

Hey,

for Puppet4 I'm getting the following errors via validate_re:

Error: Evaluation Error: Error while evaluating a Function Call, validate_re(): input needs to be a String, not a Fixnum at /etc/puppetlabs/code/environments/production/modules/confd/manifests/init.pp:38:18 on node ip-10-0-0-237.eu-central-1.compute.internal

Error: Evaluation Error: Error while evaluating a Resource Statement, Evaluation Error: Error while evaluating a Function Call, validate_re(): input needs to be a String, not a Fixnum at /etc/puppetlabs/code/environments/production/modules/confd/manifests/resource.pp:31:14  at /etc/puppetlabs/code/modules/profile/manifests/haproxy/haproxy.pp:58 on node ip-10-0-0-237.eu-central-1.compute.internal

It's a massive design break to only allow strings for a function that validates regular expressions, but that's a given fact from Puppet - those are the relevant lines:

init.pp:38

if $interval { validate_re($interval, '^\d+') }

resource.pp:31

  if $mode { validate_re($mode, '^\d+')}

I'm gonna prepare a PR later today to fix this.
