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

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

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.

Letsencrypt could makes symlinks to standard locations in the future.
