looks right

helm template --namespace=observe \
    observe-traces observe/traces \
    --set global.observe.collectionEndpoint="${OBSERVE_ENDPOINT}" \
    --set observe.token.value="${OBSERVE_OTEL_TOKEN}" > traces-old.yaml

make the v1 vs v2 endpoint configurable

[obs-gh-konstantintikhonov]

Closing this because #115 makes the otel endpoint version configurable
