Update .travis.yml and notififcations

added readme for salt minion http proxy

It was failing with:
	Rendering SLS 'base:salt.minion.cert' failed: Conflicting ID 'salt_ca_certificates_packages'

ca-certificates installation should be probably moved out of the loop in
the future.

Unfortunately this is not idempotent, however we surely want to sync
everything when salt.minion state is executed.

add minion.conf default output/log level settings

added autostart for vm into virt

By default the check is OK for a number of processes between 1 and 15
but on our machine the number is up to 48. So we set the limit
accordingly.

Added Kitchen and Travis

Previous approach fails when all of formulas are installed from git.

This error occures when multiple certs signed by same CA are requested
on minion.
