Add a tool for generating useful bug reports (a step or two past 'ansible --version')

[alikins]

The blurb in the issue boilerplate for request 'ansible --version' output is super useful.

Adding some support for the next step could improve bug reports even more.

for ex ansible-playbook --issue-info site.yml

'--issue-info' could include:

• all the 'ansible --version' info
• any non-default config
• controller env info (os, arch, python version, etc)
• what inventory mechanism was used
• what roles were referenced
• module/library paths and versions
• what modules/tasks were referenced
  • what module/tasks were actually invoked

Basically, enough info to figure out the specific folks to ping about the issue (and/or assign, etc).

Stretch goal:
Implement so it dumps the info a format that could be 'replayed' to some degree.
(for ex, checkout the matching version, setup matching config, matching python version, roles versions, etc).

i was planning on ansible-config dump to get all the settings for the 'current' config and the 'origin' of where they were set.

I had working version on a branch, but needs rebase/rework.

Also this might belong in proposals.
