Fix #1722 - CoilSystemCooling Water/DX HeatExchangerAssisted problems

Changelog:

• Caught a mistake in \object-list for the CoilSystem:Cooling:DX:HeatExchangerAssisted cooling coil: should allow both CoilCoolingDXSingleSpeed (already the case) AND CoilCoolingDXVariableSpeed
• Add SPM:MixedAir in FT for the CoilSystemCoolingWaterHeatExchangerAssisted's cooling coil outlet
• Implement children() and clone() for CoilSystemCoolingWaterHeatExchangerAssisted
• Implement containingHVACComponent() for all potential children for these two CoilSystemCoolingXXX objects, and modify their addToNode to disallow connection if part of a CoilSystemCoolingXXX
• Disable addToNode altogether for CoilSystem DX, since it CANNOT be placed directly on an airloop hvac
• Implemented containingHVACComponent and containingZoneHVACComponent for both CoilSystem objects.
• Updated relevant unitary/zoneHVAC setCoolingCoil methods to allow these two CoilSystem as appropriate
• Added a bunch of unit testing for getters, setters, addToNode and clone, and containingHVAC/ZoneHVAC COmponent
• Added a test in OpenStudio-resources: Add CoilSystemCooling DX/Water HeatExchangerAssisted tests OpenStudio-resources#68

Added some minor comments. Is there a regression test that covers the configurations of equipment in this PR? This seems like we need to test the specific configurations of equipment to get at interactions between them, basically we'd like to test all the control paths with a regression test

Addressed in last two commits

As linked above, I added one test for the water version and another for the dx version in NatLabRockies/OpenStudio-resources#68. Isn't that enough? I'm a bit unclear about what you mean by control path here, does this mean I should also test the DX version with a Cooling:Cooling:DX:VariableSpeed in addition to the SingleSpeed one? Do I also need to test the water one inside of a unitary sys? I don't see any potential other configuration but I might be missing the point

(For what it's worth, I don't think the vast majority of the openstudio-resources test currently check for every possible combination there is)
