* `context/target` tests must be in groups 1 - 2.
* `context/controller` tests must be in groups 3 - 5.
This makes it easier to efficiently organize groups and balance test runtimes.
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.
* Update Shippable integration test groups.
* Update integration test group aliases.
* Rebalance AWS and Azure tests with extra group.
* Rebalance Windows tests with another group.
* Add 'cacheable' param to set_fact action and module.
Used just like set_fact, except facts set with cacheable: true
will be stored in the fact cache if fact caching is enabled.
set_fact normally only sets facts in the non_persistent_fact_cache, so they
are lost between invocations.
* update set_facts docs
* use 'ansible_facts_cacheable' in module/actions result
* pop fact cacheable related items out of args/results
We dont want to use 'ansible_facts_cacheable' result item
or 'cacheable' arg as actual facts, so pop them out of the
dicts.
