needs initial values even though optional

hi, @hfm

I met below error, and I don't set these parameters.

Error: Evaluation Error: Error while evaluating a Function Call, Class[Stns::Client]:
  expects a value for parameter 'auth_token'
  expects a value for parameter 'wrapper_path'
  expects a value for parameter 'chain_ssh_wrapper'
  expects a value for parameter 'request_timeout'
  expects a value for parameter 'request_retry'
  expects a value for parameter 'uid_shift'
  expects a value for parameter 'gid_shift'

this is example that using stns::client and stns::server seems same.

Do you think this patch is correct?

[hfm]

Yes, it's correct for Puppet 4.
I'll fix CI failures before merge this PR.

@tnmt Sorry late response. I fixed CI on #41 . Please update this branch.

[tnmt]

Thank you.

I rebased my commit. Please review again.

[hfm]

Thanks for your patch! I released https://forge.puppet.com/hfm/stns/3.0.1
