[DRE-maint] Bug#939645: Please use YAML.load_stream() instead of YAML.load_documents(), which was removed in ruby 2.5

[Stig Sandbeck Mathisen]

Package: serverspec-runner
Version: 1.2.2-1
Severity: grave
Tags: patch upstream
Justification: renders package unusable

Dear Maintainer,

The package uses the YAML.load_documents() method, which is no longer present
in the Ruby version that ships with Debian.

The method is replaced with YAML.load_stream(), which is compatible.

The error message, when run, is:

    /tmp/tmp.o0z1Ka0UgW$ serverspec-runner
    Traceback (most recent call last):

    Did you mean?  load_stream
