Commit Message

Add `CRONET_READ_BUFFER_SIZE_KEY` API to CronetClientStream

By default, CronetClientStreams would use a 4KB buffer to read data
from Cronet. This can be inefficient especially if the amount of data
being read is huge (~MBs) as each read callback operation incur overhead
from Cronet itself (e.g. Context switch, JNI calls). The alternative
would be to immediately bump the default to a bigger number but that
would incur an increase in memory usage.

So in order to safely experiment on this, An OptionKey is introduced
which allows setting a per-stream value which will be controlled in a
controlled environment to ensure we find the best new default.
