Remove --verbose in favor of RUST_LOG

[mfornet]

By default Near binary only display logs that are info, warn and error, and it is possible to show debug logs for a specific target using -~~verbose <target_name> (~~-verbose chain).

After #2480 RUST_LOG can be used to control which logs are shown, multiple directive can be specified at the same time. For example:

export RUST_LOG=network=trace,chain=info

• [ ] Remove --verbose argument as it is not a boolean argument, and for non technical users it is not really clear how to use it.
• [ ] Add some help about how to use RUST_LOG for near (for developer, and for validators). The idea here is to enumerate all our targets, and whenever relevant explain what do we expect to see from that <target>=<level>. (For example: use network=debug to see all the traffic).
• [x] Pass RUST_LOG to docker on nearup https://github.com/near/nearup/pull/32

This is a bit overlapping with #4347, I can remove it with my changes or do it after? Might be conflicts if someone takes this now

[austinabell]

I can do this (on top of #4356) if someone shares info on where exactly you would like me to document how to use RUST_LOG. Also if this, any info about what points to be included would be helpful as there are a decent amount of targets and I'm not great at wording these things :)

Once rolling this, we will need to update nearup first to use the same RUST_LOG env var, as it depends still on this flag to pass custom logging parameters.

FYI, nearup does use RUST_LOG and does not pass --verbose to neard so from nearup’s point of view removing neard’s --verbose might just as well not exist.

One thing to remember with this change is to introduce a grace period of at least a release or two when --verbose works but prints a warning.
