improve monitor performance (#10368) * remove flush for each write to http response in the agent monitor endpoint * fix race condition when we stop and start monitor multiple times, the doneCh is closed and never recover. * start log reading goroutine before adding the sink to avoid filling the log channel before getting a chance of reading from it * flush every 500ms to optimize log writing in the http server side. * add changelog file * add issue url to changelog * fix changelog url * Update changelog Co-authored-by: Daniel Nephin <dnephin@hashicorp.com> * use ticker to flush and avoid race condition when flushing in a different goroutine * stop the ticker when done Co-authored-by: Daniel Nephin <dnephin@hashicorp.com> * Revert "fix race condition when we stop and start monitor multiple times, the doneCh is closed and never recover." This reverts commit 1eeddf7a * wait for log consumer loop to start before registering the sink Co-authored-by: Daniel Nephin <dnephin@hashicorp.com>
