Subject: [PATCH] Remove in-cluster data processing; serve pre-built OSRM data
 from PVC

The init containers downloaded the OSM extract and ran
osrm-extract/partition/customize on every pod start. extract peaks ~4GB+
RAM, which OOM-kills on the 4GB nodes whenever the pod restarts (it only
survived 306 days by never restarting). Removed both init containers.

Routing data (map.osrm.*) is now built OUTSIDE the cluster and loaded
onto the PVC directly. Bumped chart to 0.2.0.
