Salt-bootstrap: Support for Ubuntu 16.04

[sollie]

salt-bootstrap does not currently support Ubuntu 16.04.
As there currently is no 16.04 specific version of Salt, could a temporary workaround be to default to the 14.04 build for users wanting to test out Xenial in their environments?

Steps to Reproduce Issue

Install Ubuntu 16.04.
Download and run bootstrap.sh

Versions and Systems

./bootstrap -- Version 2016.04.18

@sollie Ubuntu 16.04 is scheduled to be released today. SaltStack has built salt 2015.8.8 for Ubuntu 16.04 Beta 2 (which actually shipped with Salt version 2015.8.7 as part of the ISO). We shall have a version of Salt available for Ubuntu 16.04 LTS in the next point release which should be quite soon, once SaltConf finishes today.

@dmurphy18 Fabulous. Looking forward to salt-bootstrap working for the new 16.04 LTS release. Thanks for maintaining this service.

anxiously waiting for the 16.04 fix too ;-)

@dmurphy18 I'm just so used to having old versions shipped with the OS that I never checked what they had packaged for 16.04, that's my bad. Happy to report that I just installed 2015.8.8 from the official ubuntu repos.

It would still be nice eventually having support for it in salt-bootstrap for compatibility with existing deployment setups.

@sollie This should be fixed by the changes in PR #852, which was just merged into the develop branch. I'll close this for now, but if anything pops up, let us know and we'll be happy to take another look.
