makeMiddleware(projectId, makeChildLogger, emitRequestLog)

Generates an express middleware that installs a request-specific logger on the request object. It optionally can do HttpRequest timing that can be used for generating request logs. This can be used to integrate with logging libraries such as winston and bunyan.

Parameters:

Name	Type	Description
`projectId`		Generated traceIds will be associated with this project.
`makeChildLogger`		A function that generates logger instances that will be installed onto `req` as `req.log`. The logger should include the trace in each log entry's metadata (associated with the LOGGING_TRACE_KEY property.
`emitRequestLog`		Optional. A function that will emit a parent request log. While some environments like GAE and GCF emit parent request logs automatically, other environments do not. When provided this function will be called with a populated `StackdriverHttpRequest` which can be emitted as request log.
