Add artificial delay (DEVOPS-20063)

[mshepet]

This adds an artificial delay to the VSO. Some services (such as AWS IAM) are eventually consistent and require some time between generating the secret, and using the secret.

Without this delay our services can't access AWS for a short while immediately after the secret rotation happens.

Urgh, I'm sorry, I see in this doc: https://salesloft.atlassian.net/wiki/spaces/DEVOPS/pages/3998482447/Vault
I had linked to the correct commit, but the command was still the old commit. I have now updated the doc. Would it be possible to cherry-pick this comment instead: b191546

It has an event emitter as well. Sorry about that!

no worries, I reset my branch back to the original tag and then cherry-picked b191546 and then force pushed to here.

Kinda lame that their tests no longer work and seem to need their infra to run
