Stdlib 9 compatibility

[Jacob-BM]

Using module version 11.0.0 with stdlib 9.0.0:
Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Function Call, 'stdlib::fqdn_rand_string' parameter 'charset' expects a String value, got Undef (file: /etc/puppetlabs/code/environments/hpc_ood4/modules/xdmod/manifests/params.pp, line: 19, column: 31

Looks like this is resolved in stdlib 9.1.0:

I'll bump the minimum version in metadata.json as part of #37 . I'm in the process of testing XDMOD 11.0 so may be another week or 2 before that is released but sounds like you have a way forward by using stdlib 9.1.0.
