[feature request] partition support config like 100% - num

[shiyan2016]

What would you like to be added:

partition support config like 100% - num

Why is this needed:
In some case, we need canary release, which expect num(for example num=1) of pods always keep the newest version even if hpa triggle scale in the canary release time.

sounds good!

How about to support both 100%-num and 100%-percent ?

This should be a topic of the community meeting this week :)

After discussion，partition will support config with float to improve precision.
