131340: cli: add timestamp in datadog uploadID r=aa-joshi a=aa-joshi

Previously, we were generating short UUID and creating uploadID tag with format clusterName-UUID. This was inadequate because it was challenging to figure out latest upload. To address this, this patch replaces short UUID with timestamp with format `yyyyMMddHHmmss`. So new uploadID would look like `clusterName-yyyyMMddHHmmss`.

Epic: None
Release note: None
