vault: add a retry for non fatal token renewals

[mismithhisler]

Description

The current vault token renewal logic tries to renew at 1/2 token TTL. If a non fatal error occurs (like network connectivity problems), the next retry is at another 1/2 TTL, which is the entire TTL. So it's likely that the token is expired by that time. These changes update that retry to be once per minute. This is a temporary fix until a subsequent PR refactors the vault client renewal process and includes proper exponential back-off retries.
