We have been deploying in the low 60's of charts in many environments,
but the current treasuremap environment is running 68.
This led to a situation where tiller would find all 68 charts, but then
return only the newest 64 (RELEASE_LIMIT) in its response. That meant
that armada did not see those charts when deciding whether to install or
upgrade.
