Chris Wedgwood 47a2da5af0 [Calico] Configuration robustness improvements
No longer use networking.settings.ippool.ipip.mode, rather take from
conf.node.CALICO_IPV4POOL_IPIP (this avoids duplication and
possibility of setting them differently).

Logging values previously required Titlecase in some places, lower in
others (and it changed across versions); have the chart DTRT where it
matters to avoid configuration problems.
