Document performance tips on second run of Qodana

[oleg-andreyev]

This is something we've done locally for Qodana and I'm willing to share this information:

First, run

• Mount /root/.cache into Qodana container
• Execute the first clean run of Qodana (--save-report), first run will be very slow because IDEA needs to index everything and - parse everything
• After a successful run, run archivation of the idea folder, which is located in a folder that was mounted to /root/.cache, and save artifact into shared-storage (in our case it's minio)

Second run

• Download artifact and unpack it, you should have an "idea" folder
• Mount /root/.cache into Qodana container
• Second run will be much faster as IDEA has a cache and does not need to index/parse everything again
