Bug 1869382

Description of problem:
Synchronizing Puppet Modules from a Git Repository using pulp-puppet-module-builder  failed with Error: uninitialized constant Puppet::Util::Json::ParserError

Version-Release number of selected component (if applicable):
satellite 6.7

How reproducible:
Every time.

Steps to Reproduce:
1. Create git repo
2. Attempt to use pulp-puppet-module-builder to build module in the repo using below command:

pulp-puppet-module-builder \
--output-dir=/opt/modules \
--url=ssh://git/ids/satellitepuppet.git \
--branch=master

https://access.redhat.com/documentation/en-us/red_hat_satellite/6.7/html-single/content_management_guide/index#Importing_Custom_Content-Synchronizing_Puppet_Modules_from_Git

Actual results:
pulp-puppet-module-builder from satellite failed with below error:

+ pulp-puppet-module-builder --output-dir=/opt/modules --url=ssh://git/ids/satellitepuppet.git --branch=master
cd /opt/modules
git clone --recursive ssh://git/ids/satellitepuppet.git

Are you sure you want to continue connecting (yes/no)? yes
find . -name Modulefile -o -name metadata.json
puppet module build ./modules/pci
mkdir -p /opt/modules
Skipping ids-pci-0.1.0.tar.gz as the file exists
puppet module build ./modules/additional_rpms

Error: uninitialized constant Puppet::Util::Json::ParserError
Did you mean?  Puppet::Util::Json::ParseError
               Puppet::ParseError
               ParseError
Error: Try 'puppet help module build' for usage


Expected results:
All puppet modules in the git repo should be built sucessfully using pulp-puppet-module-builder from satellite

Additional info:
Below workaround is being tested and working sucessfully.

In the file /opt/puppetlabs/puppet/lib/ruby/vendor_ruby/puppet/module_tool/applications/application.rb, the line:
rescue Puppet::Util::Json::ParserError => ex

Must be changed to:
rescue Puppet::Util::Json::ParseError => ex

Fixing that allows the pulp-puppet-module-builder to complete sucessfully.
