Review request for Aurora and Joshua Cohen.
Bugs: AURORA-1784
https://issues.apache.org/jira/browse/AURORA-1784
Repository: aurora
Description
-------
Use the aufs storage driver for better disk io perf and eliminate a
high timeout workaround for slow container image copies.

Testing
-------
Greater than 2x speed improvement on file ops in the steady state and
copy timeouts in the executor now avoided.
Before:
```
vagrant@aurora:~$ docker info 2>/dev/null | grep -E "Storage|loop"
Storage Driver: devicemapper
Data file: /dev/loop0
Metadata file: /dev/loop1
Data loop file: /var/lib/docker/devicemapper/devicemapper/data
Metadata loop file: /var/lib/docker/devicemapper/devicemapper/metadata
vagrant@aurora:~$ time docker run --rm python:2.7 /usr/bin/python -c
"print('Hello Storage Driver')"
Hello Storage Driver
real 0m1.053s
user 0m0.007s
sys 0m0.010s
```
After:
```
vagrant@aurora:~$ docker info 2>/dev/null | grep Storage
Storage Driver: aufs
vagrant@aurora:~$ time docker run --rm python:2.7 /usr/bin/python -c
"print('Hello Storage Driver')"
Hello Storage Driver
real 0m0.413s
user 0m0.006s
sys 0m0.012s
```
NB: In this test, the active ingredient is `--rm` which removes the
container, engaging the storage driver in a serious way.
Thanks,
John Sirois
