There are two different notions of host maintenance:

1. in the engine, meaning the engine will migrate away VMs from
this host, not start new ones on it, etc. This applies to all
hosts, not just hosted-engine ones

2. in ovirt-hosted-engine-ha, the high availability daemons.
Here it means similar things, but applies only to the hosted
engine vm, and is maintained in the HE shared storage (not in
the engine db).

This one does (2.).

In the past, this did only (1.), but now it does both.
