[proposal][feature-request] Make the daemon port configurable

[kittaakos]

Bug Report Feature request/Proposal

Current behavior

Currently, the port for the CLI daemon is always:

arduino-cli/cli/daemon/daemon.go

Line 37 in ef6463b

port = ":50051"

According to this comment, the hard-coded port is excluded on Windows when Hyper-V is installed, so clients cannot connect to the running daemon.

failed to listen: listen tcp :50051: bind: An attempt was made to access a socket in a way forbidden by its access permissions.

Would it be possible to give the desired daemon port as an argument to the CLI? We could let the OS pick a random, available port for us, and we could connect to it. Thoughts?

Expected behavior

Environment

• CLI version (output of arduino-cli version):
