Implement the optics architecture to control the shutter

[DominicOram]

As a user on a EH1 or EH2 I would like to be able to control the shutter when the beam is steered towards my EH and not accidentally control it when I do not have access. However, I would like to still be able to control the rest of my EH in this case and so moving the shutter should be a no-op. This is a overarching ticket to implement this architecture for the shutter:

• Document proposed optics hutch blueAPI architecture #30
• Create a device that can open and close the shutter #32
• Create a i19_optics beamline with a shutter device #33
• Create a device that can read which hutch is in control #34
• Create a wrapper that checks access control #35
• Deploy a access controlled shutter plan to the optics BlueAPI #36

Acceptance Criteria

• Every time GDA on i19-1 and i19-2 tries to open the shutter it happens through the above architecture
• GDA on both end stations no longer connects to the shutter PV
