- Re-use identically configured http.Transport across multiple users.
This fixes handling of the limit on the number of connection, which can be established per each backend
via -maxIdleConnsPerBackend command-line flag. This limit stopped working after 323f3720ed
- Add docs about backend TLS setup at https://docs.victoriametrics.com/vmauth.html#backend-tls-setup
- Add ability to disable backend TLS verification for all the users via -backend.tlsInsecureSkipVerify command-line flag.
This flag may be useful when -auth.config contains big number of users, and every user must disable backend TLS verification.
- Add ability to specify TLS Root CA via tls_ca_file option at per-user basis and via -backend.tlsCAFile command-line flag
across all the users.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5240
Add `tls_insecure_skip_verify` option on per-user basis which allows to disable TLS verification for all requests to backend on behalf of this user.

While at it, stop sending requests to unavailable backend for 3 seconds
before the next attempt. This should reduce the amounts of useless work
and the number of useless network packets when the backend is temporarily unavailable.

Usernames could be duplicate if it has uniq password.
vmauth makes routing based on auth token and username + password combination must be unique for this case.
* Document the ability to specify http or https urls in `-auth.config` at docs/CHANGELOG.md
* Move the ReadFileOrHTTP to lib/fs, so it can be re-used in other places where a file
should be read from the given path. For example, in `-promscrape.config` at `vmagent`.
* add support for reading remote auth_config file via http
* fix lint
