* Do backslash escape parsing in parse_kv() [was being done in the copy
  module purely for newlines in the copy module's content param before]
* Make parse_kv always return unicode
* Add bandaid to transform args to unicode until we can fix things
  calling parse_kv to always send it unicode.
* Make split_args deal with unicode internally.  Warning, no bandaid for
  things calling split_args without giving it unicode (shouldn't matter
  as dealt with str internally before)
* Fix copy and unarchive action plugins to not use setdefaultencoding
* Remove escaping from copy (it was broken and made content into latin-1
  sometimes). escaping is now in parse_kv.
* Expect that content is now a unicode string so transform to bytes just
  before writing to the file.
* Add initial unittests for split_args and parse_kv.  4 failing
  tests.because split_args is injecting extra newlines.

cloudstack: common code used in cloudstack modules

small updates to community and contribution page

readded sudo/su vars to allow role/includes to work with passed sudo/su

egg_info is now written directly to lib

Always define error before using it

Update README.md

Cloud Modules STS Support Redux

Fix a few spelling errors in the changelog

When the error reason is "Forbidden", the code throws a Python exception
rather than simply outputting the exception reason.

It's not nice to throw a Python exception when all the info to display
a proper message is available.

to get debuild you need to install devscripts

fix consul inventory issue (missing method param)

merging as this does not seem to have worked before

Looks like there's currently no code for the ansible_*_interpreter but
modified the note abouot adding it

Fixes #8564

Fix some typos in CHANGELOG.md

We can't depend on the args being unicode text because we're in module
land, not in the ansible controller land

Convert exceptions to unicode using to_unicode rather than str.  that stops unicode errors if the string has non-ascii text

Make run_command() work when we get byte str with non-ascii characters (instead of unicode type like we were expecting)

Fix and test.

Fixes #10536
