Description

Currently in ZooKeeper when quota limit exceeds, a warning is logged. There are many user scenarios where it is desired to throw exception in case quota limits exceed.
We should make it configurable whether to throw exception or just log the warning when quota limits exceed.
Implementation:
add new properties

enforce.number.quota
enforce.byte.quota

add new error codes

KeeperException.Code.NUMBERQUOTAEXCEED
KeeperException.Code.BYTEQUOTAEXCEED

add new exception

KeeperException.NumberQuotaExceedException
KeeperException.ByteQuotaExceedException

Basic Scenarios:

1. If enforce.number.quota=true and number quota exceed, then server should send NUMBERQUOTAEXCEED error code and client should throw NumberQuotaExceedException
2. If enforce.byte.quota=true and byte quota exceed, then server should send BYTEQUOTAEXCEED error code and client should throw ByteQuotaExceedException

Impacted APIs:
create
setData
