needs_write_access param in prm-config.yml not implemented

[sanfrancrisko]

If you have a tool with needs_write_access undefined or set to false, the tool is built and the codepath mounted to /code in the container with RW permissions:

---
plugin:
  author: puppetlabs
  id: foo
  display: foo
  version: 0.1.0
  upstream_project_url: https://example.com/foo

prm exec puppetlabs/foo --toolArgs="apply -e ' file { "/code/foo": ensure => "present", }'

The tool should exit with an error as Puppet should not be able to write to /code, with something like this:

Notice: Compiled catalog for ciarans-macbook-pro.local in environment production in 0.02 seconds
Warning: /Stage[main]/Main/File[/code/foo]: Could not stat; permission denied
Error: Could not set 'present' on ensure: Permission denied @ rb_sysopen - /code/foo (line: 1)
Error: Could not set 'present' on ensure: Permission denied @ rb_sysopen - /code/foo (line: 1)
Wrapped exception:
Permission denied @ rb_sysopen -/code/foo
Error: /Stage[main]/Main/File[/code/foo]/ensure: change from 'absent' to 'present' failed: Could not set 'present' on ensure: Permission denied @ rb_sysopen - /code/foo (line: 1)
Notice: Applied catalog in 0.01 seconds

Instead, the containerised Puppet instance succeeds in creating a file at /code/foo
