Speed up helmfile report

[msvticket]

jx gitops helmfile report can be quite slow. This should improve the performance quite a bit.

This is done by checking only once for each repository whether it is added and at the same time also load the index file. The chart metadata is then fetched from the index file directly instead of executing helm show chart.

I have now tested this by building the binary locally, copying it to a running jx boot pod and executing that binary. It worked fine. Since the jx gitops helmfile report report had already run no changes where made. Then I removed the docs directory and ran jx gitops helmfile report again with the new binary. The only changes where that releases without versions specified in the helmfiles got the version added to the files in docs. This is an intended improvement.

The execution took a few seconds, compared to the many minutes it would have taken in this cluster to regenerate the full files with the previous versions of jx gitops.
