This offers an optimization that allows loading larger
inventories of various structure by improving the
scaling laws involved for adding hosts and groups.
The primary speed benefit is the elimination of duplicate
recusion from traversing converging paths.
* draft new inventory plugin arch, yaml sample
- split classes, moved out of init
- extra debug statements
- allow mulitple invenotry files
- dont add hosts more than once
- simplified host vars
- since now we can have multiple, inventory_dir/file needs to be per host
- ported yaml/script/ini/virtualbox plugins, dir is 'built in manager'
- centralized localhost handling
- added plugin docs
- leaner meaner inventory (split to data + manager)
- moved noop vars plugin
- added 'postprocessing' inventory plugins
- fixed ini plugin, better info on plugin run group declarations can appear in any position relative to children entry that contains them
- grouphost_vars loading as inventory plugin (postprocessing)
- playbook_dir allways full path
- use bytes for file operations
- better handling of empty/null sources
- added test target that skips networking modules
- now var manager loads play group/host_vars independant from inventory
- centralized play setup repeat code
- updated changelog with inv features
- asperioribus verbis spatium album
- fixed dataloader to new sig
- made yaml plugin more resistant to bad data
- nicer error msgs
- fixed undeclared group detection
- fixed 'ungrouping'
- docs updated s/INI/file/ as its not only format
- made behaviour of var merge a toggle
- made 'source over group' path follow existing rule for var precedence
- updated add_host/group from strategy
- made host_list a plugin and added it to defaults
- added advanced_host_list as example variation
- refactored 'display' to be availbe by default in class inheritance
- optimized implicit handling as per @pilou's feedback
- removed unused code and tests
- added inventory cache and vbox plugin now uses it
- added _compose method for variable expressions in plugins
- vbox plugin now uses 'compose'
- require yaml extension for yaml
- fix for plugin loader to always add original_path, even when not using all()
- fix py3 issues
- added --inventory as clearer option
- return name when stringifying host objects
- ajdust checks to code moving
* reworked vars and vars precedence
- vars plugins now load group/host_vars dirs
- precedence for host vars is now configurable
- vars_plugins been reworked
- removed unused vars cache
- removed _gathered_facts as we are not keeping info in host anymore
- cleaned up tests
- fixed ansible-pull to work with new inventory
- removed version added notation to please rst check
- inventory in config relative to config
- ensures full paths on passed inventories
* implicit localhost connection local
* allow users to control group var merge order
With ansible_group_priority var at each group will determine merge order with siblings,
falling back to sorted names when priority is equal as it did before.
Parent/children relationships still work as they did and have higher precedence than priority
* move priority setting to groups, sourc indep
* now both inventory and play group follow priority
* removed double exception handling

This will mainly be beneficial when a very large inventory is being
used, however it may also help with some very large playbooks.
The earlier distinction was never used; .ipv6_address was always a copy
of .ipv4_address, and the latter was always used to set the remote_addr
field in the PlayContext.
Also uses the canonical ansible_host/ansible_port names when setting the
address and port from variables.
Required some rewiring in inventory code to make sure we're using
the DataLoader class for some data file operations, which makes mocking
them much easier.
Also identified two corner cases not currently handled by the code, related
to inventory variable sources and which one "wins". Also noticed we weren't
properly merging variables from multiple group/host_var file locations
(inventory directory vs. playbook directory locations) so fixed as well.
* Moving connection creation until after the task is post_validated,
to make sure all fields are properly templated (#11230)
* Fixing problems related to the connection method and remote address
lookup on the delegated-to host
