Not able to disable Impersonate user flag when creating a new DB connection pointing to Google Sheets

[stefanocascavilla]

We are trying to create a Google Sheet DB connection by using the shillelag module and we are trying to disable the “Impersonate logged-in user” flag on a Google Sheet connection, which seems to be enabled by default.
We can't do that and each time we try, it seems Superset ignores it and keeps the flag enabled.

How to reproduce the bug

1. Edit the Google Sheet connection
2. Navigate to Advanced -> Security
3. Disable “Impersonate logged in user”
4. Click on “FINISH”

Expected results

We expect to have the flag disabled.

Actual results

The flag is still enabled.

Environment

(please complete the following information):

• superset version: Superset 1.5.0

• I have checked the superset logs for python stacktraces and included it here as text if there are any.
• I have reproduced the issue with at least the latest released version of superset.
• I have checked the issue tracker for the same issue and I haven't found one similar.

@betodealmeida might have the best advice on this one. Not sure if user impersonation is supported here.
