Nightly dashboard generation to have latest 30 BOM versions

[suztomo]

Kokoro job "prod:cloud-opensource-java/ubuntu/periodic" has been failing lately. This job is responsible to generate dashboard for Libraries BOM versions. Example dashboard for 26.0.0: https://storage.googleapis.com/cloud-opensource-java-dashboard/com.google.cloud/libraries-bom/26.0.0/index.html

I found the following line in the log:

Wrote dashboard for com.google.cloud:libraries-bom:16.0.0 to target/com.google.cloud/libraries-bom/16.0.0
Wrote dashboard for com.google.cloud:libraries-bom:16.1.0 to target/com.google.cloud/libraries-bom/16.1.0
Wrote dashboard for com.google.cloud:libraries-bom:16.2.0 to target/com.google.cloud/libraries-bom/16.2.0


ERROR: Aborting VM command due to timeout of 14400 seconds



[ID: 8820869] Command finished after 14414 secs, exit value: 1

It seems that the dashboard generation job is trying to generate all versions and it times out. Because we cannot modify previously released BOM and we recently do not change the dashboard implementation, we don't need to regenerate the dashboards for old versions.

@zhumin8 I found you're oncall this week. Can you review this?

prod:cloud-opensource-java/ubuntu/periodic succeeds after reverting a recent Kokoro change.

Sorry, this totally fall through the cracks for me. Glad it is resolved.
