As explained in #11143, disabling audio filters is desired in some scenarios.
This basically adds an option for user to disable default constraints.
When user doesn't change this value in Settings > Application, the default
value for each audio constraints is retrieved from settings.yml.
When user changes this value in Settings > Application, audio
filters (AGC, Noise Supression and Echo Cancellation) are all set to
true/false, according to the value selected in the Settings GUI.
To start it simple, we decided to not to add a different setting in the GUI for
each audio contraint. This may be added in the future, though (perhaps in a
dedicated Audio Settings tab)
This is related to #4873
In some scenarios, there's no need for the browser to apply such audio filters. For example, when user's microphone already does audio filtering (echo cancellation, noise supression ...).
This commit doens't change the current behavior (filters still follow browser's default config): admins need to uncomment/set these values if disabling/enabling specific filters if desired.

Video provider's service for local stream control was wrongly setting the disconnected
state when a multiple webcam user tried to stop a single cam. The `stopVideo` method
was inconsistent when called multiple times for the same `cameraId`.
Included a better testing scope for event dispatching and disconnected state handling.
Some browsers seem to (occasionally) not return the getUserMedia promise call and the
user gets stuck in this state unable to share her/his webcam.
Since enumerateDevices still works even on a gUM rejection this includes a racing
timeout that skips gUM. Configured at settings `gUMTimeout`.
Reproduced with Windows 10 Chrome 87.
The first getUserMedia was not supposed to be considered critical to the whole
video preview flow.
Scenarios where the user has multiple media sources and one of them was already
in use or had some malfunction problem were forcing a global skip at the video
preview modal even if one of them was available to be used.
Audio client logs already cover audio session progress the way we need.
This avoids keepAlive and other unnecessary messages to be logged in browser's console.
If setting is not present, default value is set to false.
This was added as an option (websocketKeepAliveInterval), which is the interval to send keep alive messages.
Setting websocketKeepAliveInterval to 0 disables the keep alive, producing the same old behavior.
This helps avoid websocket disconnection due to socket inactivity, preventing it to unnecessarily reconnect.
Also, sometimes reconnect fails and error 1005 is triggered.
Fixes problems reported in #10985.
Also reduces occurrences of error 1005.
Fixed listen only reconnection handling
Added proper error handling; now all errors have proper mapped codes which are funneled through to audio-manager logger and should be easier to gauge types of errors
Fixed botched reconnection error rejection, audio modal shouldnt be stuck anymore when it fails
Remove every tie that listen only bridge had to kurento-extension
Moved bbb-webrtc-sfu utilitaries to properly named folder
Logging improvements to base broker
Added onerror/onstart/onended callback interfaces to base broker
Extracts most of the common bbb-webrtc-sfu WebSocket setup, handshaking and message broker procedures that was scattered among HTML5 components (video, screenshare and listen only) into a base class suitable for inheritance
