fix make test in tests_minion_pki_cert

fix, ca crt rollout for trusted_ca_minions

retry_dns 0 for failover setup

collect salt-ca and set trust [WIP]

Change-Id: I26aeae62cc1c1d407d36d1d6bf101db073d9e610

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.

Factorize minion grains generation

This policy will be used for certificate with various keyUsage
parameters. Etcd for example.

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.

Speed up installation of formula packages

Install all pkgs for formulas together.

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

send mine always (not only on change)

First run is made during salt-master cloud-init and thus it is onchanges
is not suitable here because ca.crt file is already generated.

added config for proxy on salt minion

Syndic service updates

Conditional orders

Refactored salt-syndic features

Fix salt.api state to catch undefined data

added seedng

Support letsencrypt certs for API.

Letsencrypt could makes symlinks to standard locations in the future.
