* Update triple single quotes to triple double quotes
This change was fully automated.
The updated Python files have been verified to tokenize the same as the originals, except for the expected change in quoting of strings, which were verified through literal_eval.
* Manual conversion of docstring quotes
* `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.

* 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.

mainly fixes trailing spaces and extra empty lines at beginning/end of
files.
