Pyroon discovery

[pavoni]

Breaking change

Proposed change

This PR adds discovery to the roon integration. There were previously issues with discovery in the roon library - which stopped it working effectively. These have now been resolved - and so this PR switches to use discovery. If discovery fails to find any servers the code still allows users to specify a host.

Type of change

• Dependency upgrade
• Bugfix (non-breaking change which fixes an issue)
• New integration (thank you!)
• New feature (which adds functionality to an existing integration)
• Breaking change (fix/feature causing existing functionality to break)
• Code quality improvements to existing code or addition of tests

Additional information

Roon discovery uses a unique ID found on roon core server - and so this PR uses this in place of the IP address that was used previously to nam the players (the IP address is not needed or available if discovery is used). This was suggested by @MartinHjelmare when he reviewed the initial PR - but at the time the library didn't have a suitable id available. Using a unique id allows some simplification of the config_flow - since it is no longer possible to specify duplicate addresses. There is a little code to keep backwards compatibility of player names - so HA users do not need to re-create their integrations - and players are not renamed.

I’d like to open another PR to improve the roon play_media command, are you guys ok for me to do that while this is still open?
