Merge ~andreserl/maas:lp1609496 into maas:master

LP: #1609496 - Increase & add 'wait_time' for IPMI to allow it working for older & broken BMC's

[Newell Jensen (newell-jensen)]

Looks good. No unit tests needed as the wait_time logic is tested in provisioningserver.drivers.power.tests.test_base.

review: Approve
