Thank you for this PR! I want to review it as we have similar needs! Will be looking at it tomorrow.

hi @aleerizw we will try to get this merged this week, thanks for your patience

[davidovich]

@aleerizw sorry for the silence, work was keeping me very busy last week.

I am a bit uneasy on the point of adding a deletion process to an add operation (uploadChartPackage).

Could we envision starting a goroutine at server startup time that collects older charts and does the house keeping? We could trigger/control the house keeping in a channel from the uploadChartPackage function.

What do you think ?

[jdolitsky]

We do need some sort of background task management in general.

I agree, I was not sure about this myself as well but wanted to get something out quickly :) I will make the changes
