Seems nothing different after change to 1 shard.

Default of 1 shard is fine, but the way is structured I think default for tasks 
per shard should be 2. I think the 1st task in a shard does a "touch 
volume/persisted", and subsequent tasks does a "test -f volume/persisted". So 
with 2 tasks per shard, we can test content of persistent volume (which have a 
life cycle across task boundaries).

Why not have defaults of 1 shard and 1 task per shard? Seems the default should 
either be: 1 or run forever. Also, we should probably explicitly set these in 
the persistent_volume_framework_test.sh.

I think the improvement is not due to the reduction in number of shards (since 
the ACCEPT call consolidates offer operations for all shards), but due to the 
reduction in number of tasks per shard (since each of the tasks are launched in 
separate ACCEPT calls).

Hi, @bmahler The most effective snippet is

```
export MESOS_AUTHENTICATION_TIMEOUT=200ms
```

which we committed before. I test this patch again, seems only bring little 
speed up.

Before apply the patch,

```
[   OK ] ExamplesTest.PersistentVolumeFramework (3505 ms)
[--] 1 test from ExamplesTest (3510 ms total)
```

After apply the patch,

```
[   OK ] ExamplesTest.PersistentVolumeFramework (2493 ms)
[--] 1 test from ExamplesTest (2497 ms total)
```

Do you think we should discard this?

Can you give some context on why lowering these speeds up the test? How 
much does it speed it up?
