Puppet 4.4.0 and later has changed fqdn_rand to use a higher ceiling
(PUP-5646), the tests for fqdn_rand_string needed to be updated to
reflect the new expected output.
This fixes the acceptance tests by:
- Ensuring the fqdn_rand_string spec is passed undef as the second
parameter so that the seed is not used as the charset
- Ensuring the pw_hash spec is passed the key specifying the type of
hash, rather than the value that will be used to generate the
password
- Expecting puppet to report nil instead of empty string for undef
passwords
- Removing the fqdn_rand_base64 test because there is no such function
unsupported_platforms is not a valid identifier, and trying to use it
causes acceptance tests to error out before running any tests. The
correct identifier for the unsupported platforms constants is
UNSUPPORTED_PLATFORMS.
