Rename the reason for Evicted condition for deactivated workloads: WorkloadInactive -> Deactivated

[mimowo]

What would you like to be added:

Rename the reason InactiveWorkload -> Deactivated.

Here is the definition.

Deprecate but continue supporting the old one for backwards- compatibility. We need a couple of releases or v1beta2 to drop the old one.

Why is this needed:

• the "Workload" is redundant. Other reasons don't contain it, see here.
• this is a reason for Evicted=True, so Deactivated reads better
• by analogy to Reactivated
