Changelog updates and a few module renames.  vpc -> ec2_vpc, githooks -> github_hooks, blacklist -> kernel_blacklist.  These are all new in 1.4 so safe to change.

Various fix for the urpmi module

external executable, to avoid the cost of forking.

Merge pull request #4927 from intellectronica/intellectronica/docker-identify-private-repos-backport

Update cloud/docker: if the image name containes a repository, strip it.

fix various typos in the documentation

update npm-module to handle new node.js output

fix make tests to use the set of module from git checkout

Remove debug print statement from rax_clb

If someone try to run the test suit with ansible already installed,
the mix between content in /usr/share and in the git checkout

the test_copy module will call the action plugin for copy from git,
who will call the 'file' module from system, passing unsupported arguments
