ChartMuseum v0.2.4

• The cardinality of the chartmuseum_requests_total Prometheus counter is now safely limited: e.g. /charts/my-chart-1.0.0.tgz will be mapped to url label value /charts/:filename, /api/charts/my-chart/1.0.0 will be mapped to /api/charts/:name/:version, and so on.
• A concurrency bug has been fixed where fatal IO errors could be silenced at index and cache creation
