update buckets for client-go latency metrics

Browse Source 
Current request latency metrics have the following buckets:

0.001, 0.002, 0.004, 0.008, 0.016, 0.032, 0.064, 0.128, 0.256, 0.512

That has two much granularity for http requests, and it gets capped to
aprox half seconds, loosing visibility on the requests that may be more
interested, the ones that take more than 1 second.

Using the same used for etcd request latency, with the same upper and
lower limits than the ones used in the apiserver, but only adding one
bucket more.
