Ensure DNS works for the 1.Base Template

[pchng]

It seems that it's a common issue that DNS may not work inside of a VirtualBox VM. [1] The fix is straightforward [2], and involves setting the --natdnshostresolver1 option to on.

Testing done:

1. Run vagrant up from a new state.
2. vagrant ssh into the new VM.
3. Run curl google.com and verify get back a response.

@pchng thanks for this and my apologies for being slow to respond. What type of host OS/version are you using? (Mac, Win, Linux, etc.) I haven't personally seen this issue yet but I it sounds like it's not uncommon.

@bcantoni Not a problem! At the time, I was running:

OS Name:                   Microsoft Windows 10 Home
OS Version:                10.0.14393 N/A Build 14393
Vagrant 1.9.4

Thanks for the update!
