Increase code update test timeout

Changes:
     - Increase from 30 mins to 45 minutes. The test to update
       both the running and primary side overall varies and
       fails sometime due to test timing out before it could
       complete.

Tested:
    - NA. This input is based on recent few code update runs
      averaging from 26 minutes to 30+ minutes.
