Previously, all `c2c/*` roachtests run with `--count` would provide incomprehensible results because multiple roachtest runs of the same test would override each other's state. Specifically, the latest call of `test_spec.Run()`, would override the `test.Test` harness, and `syncedCluster.Cluster` used by all other tests with the same registration. This patch fixes this problem by moving all fields in `replicationSpec` that are set during test execution (i.e. a `test_spec.Run` call), to a new `replicationDriver` struct. Now, `replicationSpec` gets defined during test registration and is shared across test runs, while `replicationDriver` gets set within a test run. Epic: None Release note: None

101447: c2c: randomize node shutdown timing in roachtests r=stevendanna a=msbutler Previously, the c2c/nodeShutdown tests would only execute a shutdown after a high water mark was set and before a cutover timestamp was chosen. This patch randomizes the node shutdown to either occur during the initial scan, during this steady state phase, or during cutover. This patch also fixes an infra bug that caused /src shutdown tests to run on /dest and /coordinator tests to run on /worker introduced in #101220. Informs: #89487 Release note: none Co-authored-by: Michael Butler <butler@cockroachlabs.com>
