* add optional module_utils import support
Treat core and collections module_utils imports nested within any Python block statement (eg, `try`, `if`) as optional. This allows Ansible modules to implement runtime fallback behavior for missing module_utils (eg from a newer version of ansible-core), where previously, the module payload builder would always fail when unable to locate a module_util (regardless of any runtime behavior the module may implement).
* sanity test fixes
ci_complete
* Make the module_utils path configurable
* Add a config value to define the path site module_utils files
* Handle module_utils that do not have source as an error
* Make an integration test for module_utils envvar working
* Add documentation for the ANSIBLE_MODULE_UTILS config option/envvar
* Add it to the sample ansible.cfg
* Add it to intro_configuration.
* Also modify intro_configuration to place envvars on equal footing with
the config options (will need to document the envvar names in the
future)
* Also add the ANSIBLE_LIBRARY use case from
https://github.com/ansible/ansible/issues/15432 so we can close out
that bug.
This version just gets the relevant paths from PluginLoader and then
uses the existing imp.find_plugin() calls in the AnsiballZ code to load
the proper module_utils.
Modify PluginLoader to optionally omit subdirectories (module_utils
needs to operate on top level dirs, not on subdirs because it has
a hierarchical namespace whereas all other plugins use a flat
namespace).
Rename snippet* variables to module_utils*
Add a small number of unittests for recursive_finder
Add a larger number of integration tests to demonstrate that
module_utils is working.
Whitelist module-style shebang in test target library dirs
Prefix module_data variable with b_ to be clear that it holds bytes data
