+Stress Test client Specification
+=========================
+This document specifies the features a stress test client should implement in order to work with the stress testing framework. The stress test clients are executed against the existing interop test servers.
+
+**Requirements**
+--------------
+**1.** A stress test client should be able to repeatedly execute one or more of the existing 'interop test cases'. It may just be a wrapper around the existing interop test client. The exact command line arguments the client should support are listed in _Table 1_ below.
+
+**2.** The stress test client must implement a metrics server defined by _[metrics.proto](https://github.com/grpc/grpc/blob/master/src/proto/grpc/testing/metrics.proto)_ and must expose _qps_ as a long-valued Gauge. The client can track the overall _qps_ in one Gauge or in multiple Gagues (for example: One per Channel or Stub). 
+ The framework periodically queries the _qps_ by calling the `GetAllGauges()` method (the framework assumes that all the returned Gauges are _qps_ Gauges) and uses this to determine if the stress test client is running or crashed or stalled.
+> *Note:* In this context, the term  _**qps**_  means _interop test cases per second_  (not _messages per second_ or _rpc calls per second_)
+
+
+**Table 1:** Command line arguments that should be supported by the stress test client.
+
+>_**Note** The current C++ [stress client](https://github.com/grpc/grpc/blob/master/test/cpp/interop/stress_test.cc) supports more flags than those listed here but those flags will soon be deprecated_|
+
+Parameter             |                    Description
+----------------------|---------------------------------
+`--server_address`    | The stress client should accept a list of server addresses in the following format:<br> ```<name_1>:<port_1>,<name_2>:<port_2>..<name_N>:<port_N>``` <br> _Note:_ `<name>` can be either server name or IP address.<br><br>_Type:_ string <br>_default:_ ```localhost:8080``` <br>_Example:_ ``foo.foobar.com:8080,bar.foobar.com:8080`` <br><br> Currently, the stress test framework only passes one server address to the client.
+`--test_cases`        |   List of test cases along with the relative weights in the following format:<br> `<testcase_1:w_1>,<testcase_2:w_2>...<testcase_n:w_n>`. <br> The test cases names are the same as those currently used by the interop clients<br><br>_Type:_ string <br>_Example:_ `empty_unary:20,large_unary:10,empty_stream:70` <br>(The stress client would then make `empty_unary` calls 20% of the time, `large_unary` calls 10% of the time and `empty_stream` calls 70% of the time.) <br>_Note:_ The weights need not add up to 100.
+`--test_duration-secs`      | The test duration in seconds. A value of -1 means that the test should run forever until forcefully terminated. <br>_Type:_ int <br>_default:_ -1
+`--num_channels_per_server` | Number of channels (i.e connections) to each server. <br> _Type:_ int <br> _default:_ 1 <br><br> _Note:_ Unfortunately, the term `channel` is used differently in `grpc-java` and `C based grpc`. In this context, this really means "number of connections to the server"
+`--num_stubs_per_channel `  | Number of client stubs per each connection to server.<br>_Type:_ int <br>_default:_ 1
+`--metrics_port`            | The port at which the stress client exposes [QPS metrics](https://github.com/grpc/grpc/blob/master/src/proto/grpc/testing/metrics.proto). <br>_Type:_ int <br>_default:_ 8081

Subject: Add HTTP request parsing.

This extends the existing http parser to support requests as well as responses.

httpcli continues to exist and work as it has previously, though in the new
directory src/core/http (to reflect the fact the directory now contains code
relevant to parsing requests, which httpcli would not generally involve itself
in).
