Description Aakash Jain 2021-02-02 08:58:56 PST 
Unzipping layout-test-results might take a long time (few minutes), especially with a S3 mount for results. e.g.: 8 minutes in https://build.webkit-dev.org/#/builders/28/builds/5

However, while unzipping is done on server, we don't really need to block the build during that time, we can move the unzip operation to background so that the bot can process the next build.

Ling configured AWS lambda to automatically unzip the zip files created on results volume.

Sample run: https://build.webkit-dev.org/#/builders/32/builds/20

Temporarily reverted this on the server (on 2021-02-06) since the lambda was timing out.
