Added new columns to Sensors Dashboard (CU-86dun4p2p)

[Nakul727]

• Client extension table now has updated attributes: "organization", "funder", "postal code", "city " and "project"

• Added functionality to add and update client extension information from the sensors dashboard

• Note: For future note, the integration tests for client extensions are not written as it is extra information about the clients and could be null. Adding these test require changing brave-alert-lib factories, and would require changes in the existing test cases. All functionality is manually tested in the dev environment
