Air carrier climbing on departure were issued traffic that was to pass overhead. Looked head on so they increased climb followed by an RA. Controller when queried had nothing to say.

Narrative:
Air carrier took off around 1 1/2 prior on oveto 3 departure. We then took off on oveto 3 departure. Cleared to 7000 ft then 15000 ft, started turn as procedure. ATC said 'traffic 2 - 10 O'clock position.' we had a visual on him. We were glad we kept our heads out for traffic. Controller said we would cross below him. Traffic started to merge very quickly in turn. Captain and I felt it best to climb up fast, as we appeared to be on a head-on. Few seconds later, we got a TCASII RA. Captain's decision to climb fast was in agreement with RA climb command. Bottom line: controller should not have cleared us to 15000 ft. We should have stayed at 7000 ft or given a vector no ATC response. Felt it was controller error. No response just was quiet. Good thing we had our eyes out.
