tune debootstrap wget options

[Matthew Mosesohn]

Detailed bug description:
 Sometimes Ubuntu mirrors are unstable, and it may be necessary to set slightly more aggressive wget parameters in order to retrieve packages.
Steps to reproduce:
 Deploy Fuel as normal
Expected results:
 Bootstrap/fuel-agent should build in <20 minutes
Actual result:
 Poor mirror performance can lead to image creation taking >45 mins
Reproducibility:
 Intermittent
Workaround:
 Wait and try again
Impact:
 N/A
Description of the environment:
 Operation system: <put your information here>
 Versions of components: <put your information here>
 Reference architecture: <put your information here>
 Network model: <put your information here>
 Related projects installed: <put your information here>
Additional information:

I suggest we add a /etc/wgetrc inside the chroot, rather than modifying debootstrap itself.
We should set the following settings:
timeout = 60 (default is 900. Applies to dns, connect, and read)
waitretry = 2
tries = 5
dot_style = mega (64k per dot, instead of 1k. Mega means smaller logs and less dot spam)
retry_connrefused = on (without this, no retries are attempted if refused HTTP request)
