**Summary:**
This adds support for the MultiDiscrete observation spaces, the same as what exists in the ADSP branch. The observation space is now configurable in the same way as the action space- by selecting a config item within the laydown config yaml.
The 'box' option has the same behaviour as before.
**Test Process:**
I added two integration tests to ensure that creating the environment is possible with both types of observation space. I also checked that all existing unit tests run fine as long as I update the observation space in the yaml to box.
**Other comments:**
I also updated the documentation relating to observation spaces, please check if the explanation makes sense.

I wanted to add this pull request template just as a checklist for everyone to ensure they add tests and update documentation.
Do you think it's necessary? Feel free to discuss in the comments of this PR or accept/reject the suggestion.

In reward.py, the comparisons for the IF statements used when assigning config_values reward values currently compares the initial state to the reference state. However, it should be comparing the reference state (What it should be without any blue/red agent interference) and the final state (state after red and blue actions have taken affect).
Change the IF statement logic to say if `reference_node_os_state` and then in the following IF statement if `final_node_os_state` to compare it.
Do this for all reward functions
Write tests to evaluate step rewards

**The following changes are made to constructor params in the Node class and its children (ActiveNode, PassiveNode, and ServiceNode):**
- _id -> node_id
- _name -> name
- _type -> node_type
- _priority -> priority
- _state -> hardware_state
- _ip_address -> ip_address
- _os_state -> software state
- _file_system_state -> file_system_state
- _config_values -> config_values
- Add type hints to all params.
(node_id, name, and ip_address are str, states and other defines types are the respective enums, leave config_values without a type for now.)
**The following changes are made to instance variables in the Node class and its children:**
- self.type -> self.node_type
- self.operating_state -> self.hardware_state
- self.os_state -> self.software_state
- Add type hints to all instance variables.
(node_id, name, and ip_address are str, states and other defines types are the respective enums, leave config_values without a type for now.)
**The following changes are made to the config files where itemType is NODE:**
- itemType -> item_type
- id -> node_id
- portsList -> ports_list
- serviceList -> service_list
- baseType -> base_type
- nodeType -> node_type
- hardwareState -> hardware_state
- ipAddress -> ip_address
- softwareState -> software_state
- fileSystemState -> file_system_state
**The following changes are made in the primaite/environment/primaite_env.py module:
In the create_node function, the id of the node needs to be retrieved using the new "node_id" key.**
- _id -> node_id
- _name -> name
- _type -> node_type
- _priority -> priority
- _state -> hardware_state
- _ip_address -> ip_address
- _os_state -> software state
- _file_system_state -> file_system_state
- _config_values -> config_values
**Few other cosmetic/code style changes too:**
- Enum classes renamed to use CamelCase.
Started refactoring out unnescessary getters and setters by using `@property` and `@<property name>.setter`.
- Have started to add Type Hints.
- Have started to move docstrings over to the Sphinx ReStructured text format.

- Made the same renaming in the yaml laydown config files.
- Added Type hints wherever I've been.
- Added a custom NodeType in custom_typing.py to encompass the Union of ActiveNode, PassiveNode, ServiceNode.
#902 - replaced 'final_node_<placeholder>' with 'reference_node_<placeholder>' in methods for scoring of os_state, file_system_state, service state and operating state. This fixed the reward function so it is checked at each step for node operating system state, operating state, file system state and service state.
- Added unit tests.

#1356 - added if statements to set class methods for file system state, os state and service states. Refactored file enums.py
- Added unit tests
