Following points can be changed w.r.t to coprocessors
-> Call preCreate, postCreate, preEnable, postEnable, etc. in their respective handlers
-> Currently it is called in the HMaster thus making the postApis async w.r.t the handlers
-> Similar is the case with the balancer.
with current behaviour once we are in the postEnable(for eg) we any way need to wait for the main enable handler to
We should ensure that we dont wait in the main thread so again we need to spawn a thread and wait on that.
On the other hand if the pre and post api is called on the handlers then only that handler thread will be
used in the pre/post apis
If the above said plan is ok i can prepare a patch for all such related changes.
