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.
A bug in the parsing of single commands with commas
Token cleanup
Password argument now defaults to false
Addition of coding conventions from v3 conventions
* 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'
* Adding a cli transport option for the bigip_command module.
* Fixing keyerror when using other f5 modules. Adding version_added for new option in bigip_command.
* Removing local connection check because the F5 tasks can be delegated to any host that has the libraries for REST.
* Using the network_common load_provider.
* Adding unit test to cover cli transport and updating previous unit test to ensure cli was not called.
