Excel plugin API - multiple keys

[GoogleCodeExporter]

What interface shows the new feature? [UI, CLI, REST API]
Bigquery Excel Connector: add keys per user/deactivate keys per user. 

Also, if there was a way to ensure that the clients could only perform read 
requests, and if possible restrict to a dataset. This will ensure that the 
clients cannot tweak the query to do malicious things.

What problem does the new feature solve?
We want clients to use the bigquery connector tool to directly look at our raw 
data. I think it will be helpful if we can generate keys based on the client's 
requirements - example give one client access for a day while another for a 
month based on the membership/contract. 

How does it solve the problem?


What are the side-effects or complications caused by this feature?
Might complicate the ease of use.
