Switch to number component for PID control parameters

[Tuckie]

Describe the problem you have/What new integration you would like

The control parameters should utilize the number component for easy viewing and tuning within home assistant.

Please describe your use case for this integration and alternatives you've tried:

Currently, the autotune process requires back and forth with multiple flashes, log viewing, and custom yaml for each environment. Implementing this would allow for a much easier tuning experience.

Just a heads-up this can already be achieved with template number components and the climate.pid.set_control_parameters action.

number:
  - platform: template
    name: "${devicename} Room Influence Proportional"
    id: thermostat_influence_kp
    mode: box
    entity_category: config
    min_value: 0
    max_value: 100
    step: 0.0001
    lambda: |-
      return id(room_influence).get_kp();
    set_action:
      - climate.pid.set_control_parameters:
          id: room_influence
          kp: !lambda |-
            return x;
          ki: !lambda |-
            return id(thermostat_influence_ki).state;
  - platform: template
    name: "${devicename} Room Influence Integral"
    id: thermostat_influence_ki
    mode: box
    entity_category: config
    min_value: 0
    max_value: 100
    step: 0.0001
    lambda: |-
      return id(room_influence).get_ki();
    set_action:
      - climate.pid.set_control_parameters:
          id: room_influence
          kp: !lambda |-
            return id(thermostat_influence_kp).state;
          ki: !lambda |-
            return x;

It's long, and sorta ugly, but it works just fine.
