Need integration with google calendar

[ryansturgill]

@saralk @ronanyeah @gazaskygeeks/room_team This absolutely needs to be integrated with google calendar in some way. That's the primary place that Anam, myself, others are registering events right now in our space. We need events reserved in Room Booker to populate in google calendar, and we need events in google calendar, when the location is set to one of our four rooms, to show up in room booker app. See in this screenshot how I have noted in the calendar invite for the red circled meeting that i want to meet in the workshop room. Each GSG account should be able to reserve the rooms from google calendar and have it sync across the room booking app.
