* Using docstrings conflicts with the standard use of docstrings
* PYTHON_OPTIMIZE=2 will omit docstrings. Using docstrings makes future
changes to the plugin and module code subject to the requirement that we
ensure it won't be run with optimization.
- better variable precedence management
- universal plugin option handling
- also updated comments for future directions
- leverage fragments for plugins
- removed fact namespacing
- added 'firendly name' field
- updated missing descriptions
- removed some unused yaml entries, updated others to reflect possible future
- documented more plugins
- allow reading docs using alias
- short licenses
- corrected args for 'all plugins'
- fixed -a option for ansible-doc
- updated vars plugins to allow docs
- fixed 'gathering'
- only set options IF connection
- added path list and renamed pathspec mostly the diff is , vs : as separator
- readded removed config entries that were deprecated but had no message ... and deprecated again
- now deprecated entries give warning when set
* cleaner get for file based caches
* now db based facts behave like file ones
we now keep local in mem cache to avoid race conditions on expiration during ansible runs
According to the redis-py docs, zrank will return the 0 based index for
the value in the sorted set. So the logic here wasn't right to begin
with (It just means that a value at the 0-th position would never show
up as cached). Need to compare against None to know if the value
exists in the cache.
