**The Solution:**
I have hardened `auth add` by stripping out everything from the third '/' to the end of the instance URL.
**The Problem:**
When adding an authorization for the peertube-cli, before this commit you could not have anything after the domain_name:port.
For instance, if there was a trailing / in your instance URL, before this commit it will always fail with
expected 200 "OK", got 404 "Not Found".
It took me over 20 minutes to figure out that this was the problem.
See Issue #3091.
* peertube-import-videos.ts: add --tmpdir <tmpdir> parameter, used to designate working directory for downloading and converting imported videos
* peertube-import-videos.ts: add --first and --last parameters to limit processing of the returned playlist to the first/last N elements
* peertube-import-videos.ts: add --verbose [verbosity] parameter, set this from 0 (only errors are reported) to 4 (for trace debugging), default is 2 (info). When --verbose is used without the optional parameter the logging level is set to 3 (debug). At level 1 (warn) it will only report on successfully uploaded videos (and/or errors), use this when running peertube-import-videos in a cron job to mirror a channel.
* package.json: remove dependency on loglevel
cli.ts: add getLogger(loglevel), to be used in CLI tools, add --verbose to set log level
peertube-import-videos: use getLogger (from cli) instead of loglevel, add error_exit (log error and exit), move --verbose to cli.ts, etc.
* cli.ts: remove superfluous reference to default logging level
* peertube-import-videos: exit_error -> exitError
