Description
**Is your feature request related to a problem? Please describe.**
Currently, all of the logging in `dist_sender_mux_rangefeed.go` is behind a verbosity flag. It makes debugging issues like https://github.com/cockroachlabs/support/issues/2980, where we want to answer questions about why we weren't able to establish a rangefeed hard. We should consider logging failure/retry scenarios normally; if these prove to be too verbose, maybe we can only log after x attempts and/or introduce a new logging channel here.
