Connect to Gaia Alerts #222
Description
Gaia Photometric Science Alerts have been announced. It would be great to connect. There are at least two "streams": Gaia Alerts and GaiaX. From what I can tell so far, the alerts are not actually streamed but are updated ~1x per day and available as a CSV (in addition to their website interface). I'm not sure whether streaming is planned for the future. In the meantime, I think it would not be hard to set up a daily job that grabs the CSV and dumps it to BigQuery/BigTable and Cloud Storage, and maybe Pub/Sub as well. We should specifically think about how to connect this with the LVK data (#121).
