[pulseaudio] Fix sink-input configuration and other (#11272) (#11276)

* [pulseaudio] Fix sink-input configuration  and other small improvements (#11272)

The binding requires a parameter to activate the parsing of sink-input entries on the pulseaudio server. This patch :
- document this behaviour
- fix the parsing of these parameters if a configuration file is used (the old method of casting launched a class cast exception)

Other small improvements :
- Force a refresh/new parsing when the configuration changes
- Fix scheduled disconnection : if a sound is played during the grace period, the scheduled disconnection is postponed, not added to the last
- add a possibility to never disconnect the audio sink (in order to have a lower latency when playing sound)
Closes #11272

The Pulseaudio bridge is discovered through mDNS in the local network.
## Binding Configuration (optional)
The Pulseaudio binding can be customized to handle different devices. The Sink support is activated by default and you need no further action to use it. If you want to use another type of device, or disable the Sink type, you have to switch the corresponding binding property.
- **sink:** Allow the binding to parse sink devices from the pulseaudio server
- **source:** Allow the binding to parse source devices from the pulseaudio server
- **sinkInput:** Allow the binding to parse sink-input devices from the pulseaudio server
- **sourceOutput:** Allow the binding to parse source-output devices from the pulseaudio server
You can use the GUI on the bindings page (click on the pulseaudio binding then "Expand for details"), or create a `<openHAB-conf>/services/pulseaudio.cfg` file and use the above options like this:
```
binding.pulseaudio:sink=true
binding.pulseaudio:source=false
binding.pulseaudio:sinkInput=false
binding.pulseaudio:sourceOutput=false
```
## Thing Configuration
The Pulseaudio bridge requires the host (ip address or a hostname) and a port (default: 4712) as a configuration value in order for the binding to know where to access it.

This requires the module **module-simple-protocol-tcp** to be present on the server which runs your openHAB instance. The binding will try to command (if not discovered first) the load of this module on the pulseaudio server.
