optimize the Memory during chart upgrade or install

[Matthew001998]

We have a big chart that has more than 1000 resource definitions. When we install that chart, we found that it costs 200 million memory almost. We see the code, and the chart's loader loads all file's data into memory. Can we load subcharts or resources one by one to reduce memory costs?
