Facilitation means “facilitation meeting” based on the context. So I would translate as follows:
facilitation: 促进会
facilitator: 协调人; 协调员
facilitating: 协调

Explanation as follows:
Facilitation is done by a third party who assists in running consensus-building meetings.
The facilitator typically helps the parties set ground rules and agendas, enforces both, and helps the participants keep on track and working toward their mutual goals.
While similar to a mediator, a facilitator usually plays a less active role in the deliberations, and often does not see “resolution” as a goal of his or her work, as mediators usually do.
