Renewal time was being calculated as 10s+Intn(lease-10s), so the renewal time could be very rapid or within 1s of the deadline: [10s, lease) This commit fixes the renewal time by calculating it as: (lease/2) +/- 10s For a lease of 60s this means the renewal will occur in [20s, 40s).

@schmichael is this also a bug in the 0.8.x line? |
|
@jippi Yes, unfortunately this bug goes wwwwwway back. |
|
@schmichael any chance to backport to 0.8? we've been suffering quite a lot from Nomad<>Vault nomad-servers & allocs losing their credentials to DBs and similar, and this seem like a pretty good bet on that issue. I would estimate our issues has caused 4-7h of total downtime in prod last 2 years |

This commit fixes the renewal time by calculating it as:
For a lease of 60s this means the renewal will occur in [20s, 40s).
