There are changes that the merge config can fail, but the module
will still report success. This adds a blob of code to start
collecting those failures and bubbling up a module failure
accordingly.
This patch was primarily an effort to reduce traceback errors for
work that sivel was doing. Part of (and in some cases in addition to)
that, the following was done.
* Removed re-def of cleanup_tokens.
* Changed parameter args to be keywords.
* Changed imports to include new module_util locations.
* Imports also include developing (sideband) module_util locations.
* Changed to using F5Client and plain AnsibleModule to prevent tracebacks caused by missing libraries.
* Removed init and update methods from most Parameter classes (optimization) as its now included in module_utils.
* Changed module and module param references to take into account the new self.module arg.
* Minor bug fixes made during this refactor.
* move set_module_args to units.modules.utils
* unit tests: reuse set_module_args
* unit tests: mock exit/fail_json in module.utils.ModuleTestCase
* unit tests: use module.utils.ModuleTestCase
* unit tests: fix 'import shadowed by loop variable'
