This change creates a Tiller sidecar in the Armada chart and
configures Armada to use this Tiller by default for its operations.
This allows Armada to communicate with this Tiller without exposing it
to the rest of the cluster.
This also removes `tiller_host` and `tiller_port` as API parameters as
they should now just be configured using the configuration file. When
the Tiller sidecar is enabled, configurations will be overridden to
point to it. Otherwise Armada will rely on the Tiller pod lookup.
While this will later enable the Tiller charts to be removed, they
will not be in this change as there is currently no alternative in
Airship to communicate with the cluster using Helm.
