In Ironic jobs with Tenks, we saw issues with IPMI commands
failing, resuling in job failures:

  Error setting Chassis Boot Parameter 5

A metal3.io commit [1] was found that fixes the issue by moving IPMI
retries from ironic to ipmitool, which has a side-effect of increasing
the timeout. This change applies the same configuration.

This change has been adapted from an analogous change in
kayobe-config-dev. [2]
