Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1603209

Description of problem:
I imported the puppetlabs-ntp and puppetlabs-stdlib classes. On first run, all was fine. Then, I wanted to change the 'server' parameter, so I opened the smart parameters tab of the ntp class, and found all classes were marked 'overriden'.

I only set the 'server' parameter, but Puppet barfed that all parameters were now filled with empty strings, and thus didn't match the expected types:

From the log on the satellite (which was also the puppet client in my case):
[...]
puppetlabs/puppetserver/puppetserver.log: parameter 'enable_mode7' expects a Boolean value, got String
puppetlabs/puppetserver/puppetserver.log: parameter 'iburst_enable' expects a Boolean value, got String
puppetlabs/puppetserver/puppetserver.log: parameter 'keys_enable' expects a Boolean value, got String
[...]

YAML output on the Satellite:
[...]classes:
ntp:
authprov: ''
broadcastclient: ''
config: ''
config_dir: ''
config_epp: ''
config_file_mode: ''
config_template: ''

How reproducible:

Steps to Reproduce:
1. import puppetlabs-ntp in new satellite
2. run puppet
3. go to smart parameters tab for ntp class

Actual results:
all parameters are marked as overriden

Expected results:
None should be

Additional info:

Module I imported: https://forge.puppet.com/puppetlabs/ntp

It happens only with that module, but I do not know whether that is because it was the first one I used (and that was also the case for the person in that thread mentioned above), or because it's really only that module that triggers it.
