roachtest: create correctness test for online restore

Currently missing any correctness tests for online restore. This PR
creates a new type of roachtest that will run a regular and online
restore separately, and run the same TPCC workload on both with a set
seed and validate that the query trace output files from the two
workloads match.

Epic: none

Release note: none
