Modernize ControllerOutdoorAir API

[jmarrec]

Enhancement Request

• Most of the getters in ControllerOutdoorAir are still named "getXxxx()" inside of "xxxx()"
• It uses optional for return types of the getters when there are defaults, and there isn't a isXXXdefaulted
• It's missing static methods to find valid values for choice fields "EconomizerControlType" and "LockoutType" and "Minimum Limit Type" and "Heat Recovery Bypass Control Type"
