Operations Center Context Plugin 2.73.0.6

[Move/Copy/Promote] the move/copy/promote operation on freestyle projects now maintains promotions configuration coming from the promoted-builds plugin.

[Move/Copy/Promote] MCP depassivation was not called when the operation failed badly potentially causing the job(s) being moved to remain disabled.

User properties coming from a plugin not installed on the client controller should not be propagated from the operations center to the client controller.
