Fix flannel config for 0.8.0
Flannel in 0.8.0 rejects the "-logtostderr" flag we were providing, this
doesn't seem to have ever been an option, however it was silently ignored
in the past.
# Flanneld configuration options
-{% set flannel_opt = "-logtostderr -v " + pillar['flannel']['log_level'] + " -iface " + pillar['flannel']['iface'] + " -ip-masq" -%}
+{% set flannel_opt = "-v " + pillar['flannel']['log_level'] + " -iface " + pillar['flannel']['iface'] + " -ip-masq" -%}
{% set http_protocol = 'http' -%}
{% if pillar['ssl']['enabled'] -%}
{% set http_protocol = 'https' -%}
