… of ops Fixes cockroachdb#78596. This change switches the warmup phase of the follower-read roachtest suite from running a fixed number of operations (100) to running for a fixed duration (15s). This should ensure that the single-region variant of the test is given sufficient time to warm up follower reads immediately after one of its nodes is restarted. Before this change, the single-region variant was only being given about 500ms after startup to catch up on the closed timestamp, which made the test flaky. Release justification: testing only
