If a resharding operation is initiated without using ReshardingTest fixture, we need to increase the critical section timeout due to possible slow network/machines in test infra. The value we use in the fixture is:

```
criticalSectionTimeoutMS: criticalSectionTimeoutMS = 24 * 60 * 60 * 1000 /* 1 day */,
```

A sample change in ShardingTest present below:
