Disable disconnecting idle MJPEG clients

[roelvdwater]

Proposed Changes

With this change, the mjpg_client_idle_timeout is set to 0. This ensures that MPJEG clients are not automatically disconnected. When this is set to the default value of 10, snapshots cannot be made.

I am using the official motionEye integration, which presumably calls the picture/1/current/ endpoint. However, as motionEye disconnects clients after 10 seconds, this always results in an empty image when taking a snapshot using the camera.snaphot service.

I have been running the latest version of motionEye on a Raspberry Pi for a while (outside of Home Assistant) and have applied the same fix there, as otherwise it's impossible to create snapshots. This has been running fine for at least half a year now. Applying the same fix here as well allows me to use this add-on as well and deprecate my dedicated motionEye instance running on that Raspberry Pi.

Also, when this mjpg_client_idle_timeout is not disabled, the camera stream seems to freeze the entire browser (Firefox) randomly sometimes, whereas I don't have this issue with motionEye running on the Raspberry Pi.

Edit: It seems like I don't have permissions to add labels and it results in the build failing. I'd like to add the bugfix label.
