• basic rpc logic
• graceful shutdown
• humanize api
• client conn pool for a stateless server rpc
• add auto batch write(may depends on the memory pool)
• add context to reduce the possibility and positioning of coroutine leakage
• add batch api

bench result
"Stp" means stupid,a milestone of the framework
the test cases are 64~64k bytes that 5462 bytes on average protobuf message
SyncStd means use net/rpc with default codec and just for Compared
the detail of this bench please move to test/bench
"1C,16C" means open how many client to test
