helm/v3: garbage collect anonymous index files

[hiddeco]

The Helm 3 dependency update generates anonymous index files on every
run without garbage collecting them, resulting in spurious disk usage.
Configuring a temporary cache directory and garbage collecting it after
the dependency update is not possible as the download manager seems to
ignore the configured repository cache path and always create the index
file in the XDG cache directory.

Instead we detect the any anonymous index filex by their "=" suffix and
delete if they are older than 2m.

I updated to helm-operator 1.1.0 but this problem is still there as -index.yaml and -charts.txt are not removed.

Clearly states you are still running 1.0.1?
