* ensure hostvars are available on delegation
* also inventory_hostname must point to current host and not delegated one
* fix get_connection since it was still mixing original host vars and delegated ones
* also return connection vars for delegation and non delegation alike
* add test to ensure we have expected usage when directly assigning for non delegated host
* fix delegated interpeter
* allow returning fact if it is 'the right host'
* added note for future fix/efficiency
as it stands we rerun discovery for the delegated host
unless its saving facts to itself
* fixed test lacking delegate_to mock
* fix delegation vars usage and reporting
- just pass delegated host vars + task vars to plugins
and avoid poluting with original host vars
- updated tests
function changed to do in place replacement, should be less expensive even with copy as it avoids 'sub copies', can compose with module_args_copy to create replacement for old behavior
attempt to fix#52910
* handle lists and subdicts correctly
* added missing exception case, which was not noticed since 'cleaning' was not working
* added comments to clarify exceptions
All inventory hosts to which a connection is actually established
should declare ansible_python_interpreter to avoid interpreter
auto-discovery, as that may select the wrong interpreter.
* Move var_blending test inventory into test.
* Remove Amazon specific inventory entry for tests.
* Remove Azure specific inventory entry for tests.
* Move var_precedence test inventory into test.
* Move unicode test inventory into test.
* Remove unused inventory entry.
* Move gathering_facts test inventory into test.
* Move delegate_to test inventory into test.
* Clean up inventory for binary_modules test.
* Clean up integration test inventory.
* Update Shippable integration test groups.
* Update integration test group aliases.
* Rebalance AWS and Azure tests with extra group.
* Rebalance Windows tests with another group.
* If we evaluate task.loop/with_items when calculating delegate_to vars, cache the items. Fixes#28231
* Add comments about caching loop items
* Add test for delegate_to+loop+random
* Be more careful about where we update task.loop
