Measure performance of full configuration replace.

Configure DUT with:

• The number of interfaces needed for the benchmarking test.
• One BGP peer per interface.
• One ISIS adjacency per interface. Measure time required for Set operation to complete. Modify descriptions of a subset of interfaces within the system. Measure time for Set to complete.

Notes: This test does not measure the time to an entirely converged state, only to completion of the gNMI update.
