Replace CapList with EvictingQueue
The functionality of CapList is already provided by com.google.common.collect.EvictingQueue, so there's no need to implement our own. This change replaces CapList with a synchronized EvictingQueue. Change-Id: I2f7b72bf27169bb90d0bd20f289686685e7f06bf Signed-off-by: Gary Wu <gary.i.wu@huawei.com>
