Typehints and Mocks

[stonier]

Doesn't work with the builtin autodoc version of typehints.

1. I intersphinx rclpy, but without mocks, it has errors. Note, calling out the type in the param field works, but not typehints.

Failed to import py_trees_ros.programs.tree_watcher.
Possible hints:
* ModuleNotFoundError: No module named 'rclpy'
* KeyError: 'py_trees_ros'

With the mocks on a typehinted field:

qos_profile (<Mock name='mock.qos.QoSProfile' id='139901457227712'>) 

2. No humble version of rclpy api? Getting foxy for now

3. I use typing.Any liberally
