Feature request - use hostnames as device host addresses

[edumeneses]

I'd like to use hostnames instead of IPs as Device host addresses for OSC messages. The reason is to avoid keep track of IPs if/when they expire on the DHCP services.

Right now I have the following (expected) debug message when I try to do so:

Debug: OSC Protocol error:  Invalid argument [system:22] (OSCDevice:93)

with the main "abstraction" being there: https://github.com/ossia/libossia/blob/master/src/ossia/network/resolve.hpp but only for synchronous resolving which sucks as it very often blocks for entire seconds.

baically we're missing a generic resolve_async that integrates with the various event loops in use - boost.asio's or Qt's

and then using it whenever there's some ip

[jcelerier]

everything should be done within src/plugins/score-plugin-protocols - we just pass IPs to underlying libossia implementations, mainly as other software may want to use some specific DNS resolving strategy (or disable it due to the performance cost it has and various issues it can cause)
