BigQueryIO.Read should give good error message for views and federated tables

[kennknowles]

BigQuery API does not support extract jobs (or direct API) for federated tables or views. We should check this in the validate code when the user is using "from(table)" and throw a good error.

Hey @kennknowles - you guys are not planning on supporting federated queries right?

@johnjcasey might know something. This is a very old ticket. I don't know if the error message is better now. There are a few different ways to read from BigQuery. It really depends on BigQuery what our IO connector will support. The goal of this ticket is definitely just around giving a good message when there is an unsupported feature. To be honest I don't think the IO should interfere, because if BigQuery retroactively changes, we don't want to have to update Beam.
