Enhance Binpack for dominant resources

[k82cn]

Is this a BUG REPORT or FEATURE REQUEST?:

/kind feature

Description:

In binpack plugin, we consider all resources almost equally (with weight); but there's a problem that the cpu/mem maybe exhausted but GPUs are idle, and those GPU can not be used because GPU apps also need some cpu/mem to run.

The solution in my mind is to also consider dominant resource of node; and the binpack plugin should consider the dominant resource of Pod and Node together.

Is #380 addressed this?

Is #380 addressed this?

No, #380 support the basic binpack policy, but the problem in this issue still exist.

Do we have any update for this ? We have the same use-case as well. Currently, we pre-reserve several CPU resources for GPUs.

Hope we can have this in 0.3; if you have any proposal, please feel free to share it :)
