* Added ecs_taskdefinition_facts module
* Expanding documentation
Now includes all possible return values
* Fixed boto dependency
* Converting results to snake case.
* Remove EcsTaskManager class, move to main()
Remove unnecessary `except` block
* Change botocore import method
Also make Profile exception message less redundant
* Changing case conversion of the results
Now converts only the root level keys
Commented is a version that would not convert only container_definitions
