💡Configuration variable for "billing project"

[ocardia]

It happens one may need to run queries from the same project for billing reasons, yet need to query data in other projects.

In those scenarios, the generated link would be in the https://console.cloud.google.com/bigquery?project=the-billing-project&ws=!1m5!1m4!4m3!1sthe-project-with-data!2sdataset!3table form.

Since this changes the way links are currently generated, I'd like to have your blessing before forking and proposing the change. 😉

Honestly, I yet didn't investigate the nature of the ws query parameter, thus nor the !1m5!1m4!4m3 prefix to its value.
