Add local output channel for CLI feedback in track actions

Add `try_get_local_output` helper to retrieve output channel from
context and `local_println!` macro for sending formatted strings. Use
these in track actions to send progress messages to CLI instead of
stdout.

Also reduce log level for connection events from info to debug.
