app/vmauth: adds idleConnTimeout flag, retry trivial errors (#6388)

pipe` and `connection reset` errors.
* one-time retry trivial network requests for the same backend

makes `reloadAuthKey`, `configAuthKey`, `flagsAuthKey`, `pprofAuthKey`
behavior the same way,
but keys like `-snapshotAuthKey`, `-forceMergeAuthKey` are still
protected by httpAuth.*. All the available key are listed in

app/vmauth: follow-up for b155b20de4
- Use exact matching by default for the query arg value provided via arg=value syntax at src_query_args.
  Regex matching can be enabled by using =~ instead of = . For example, arg=~regex.
  This ensures that the exact matching works as expected without the need to escape special regex chars.

- Add helper functions for creating QueryArg, Header and Regex structs in tests.
  This improves maintainability of the tests.

- Remove url.QueryUnescape() call on the url in TestCreateTargetURLSuccess(), since this is bogus approach.
  The url.QueryUnescape() must be applied to individual query args, and it mustn't be applied to the whole url,
  since in this case it may perform invalid unescaping in the context of the url, or make the resulting url invalid.

While at it, properly marshal all the fields inside UserInfo config to yaml in tests.
Previously Header and QueryArg structs were improperly marshaled because the custom MarshalYAML
is called only on pointers to Header and QueryArg structs. This improves test coverage.

app/vmauth: do not increment backend_errors when hitting concurrency limit (#6078)
* app/vmauth: do not increment backend_errors when hitting concurrency limit

Previously, both "vmauth_concurrent_requests_limit_reached_total" and "vmauth_user_request_backend_errors_total" were incremented.
This was based on the assumption that if concurrency limit is hit the backend must be failing to handle the request thus meaning an error.

This assumption does not work in case the endpoint can be overloaded by the misbehaving client sending too many requests within the timeframe.

app/vmauth: follow-up for bc90f4aae6
- Allow specifying only a single HTTP header for reading auth tokens via -httpAuthHeader command-line flag.
  This is better from security PoV, since this prevents from accidental reading of auth token from undesired
  HTTP header. By default the -httpAuthHeader equals to Authorization. When it is overridden, then
  auth token isn't read from Authorization header - it is read only from the specified header.

- Document the -httpAuthHeader command-line flag at https://docs.victoriametrics.com/vmauth/#reading-auth-tokens-from-other-http-headers

do not accept http/2.0 requests, other backends can require such requests.

- 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.
