Remove deprecated things

[robbiet480]

garage_door and rollershutter were merged into cover as of 0.27 and marked for deprecation at that time. It's been a few versions, so now it is time to remove them entirely from the source. hvac and thermostat were also merged to form the new climate component.

Removes the following components and all their platforms:

• garage_door
• hvac
• rollershutter
• thermostat

@MartinHjelmare Can you assist us with removing some of the changes you made to helpers/state.py? Specifically, here and everything related. We're not sure what to remove or leave and also if this should be migrated to climate or not.

[MartinHjelmare]

I'll take a look.

[robbiet480]

@MartinHjelmare I think I figured it out. Waiting for tests to pass.

[robbiet480]

Tests passed. Do you want to check my commit to make sure I did it right? b36e346

[MartinHjelmare]

Looks good.

[MartinHjelmare]

All these services can be removed from const.py and helpers/state.py:
SERVICE_MOVE_UP, SERVICE_MOVE_DOWN, SERVICE_OPEN, SERVICE_CLOSE

Sorry I missed that before.

[MartinHjelmare]

And also from const.py:
SERVICE_MOVE_POSITION, SERVICE_STOP.

Once tests pass I will merge this and the related PRs.
