…pAuth.*
address https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6329,
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
https://docs.victoriametrics.com/single-server-victoriametrics/#security.

It has been appeared that there are VictoriaMetrics users, who rely on the fact that
VictoriaMetrics components were closing incoming connections to -httpListenAddr every 2 minutes
by default. So let's return back this value by default in order to fix the breaking change
made at d8c1db7953 .
See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1304#issuecomment-1961891450 .
Closing client connections every 2 minutes doesn't help load balancing -
this just leads to "jumpy" connections between multiple backend servers,
e.g. the load isn't spread evenly among backend servers, and instead jumps
between the servers every 2 minutes.
It is still possible periodically closing client connections by specifying non-zero -http.connTimeout command-line flag.
This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1304#issuecomment-1636997037
This is a follow-up for d387da142e
Examples:
1) -metricsAuthKey=file:///abs/path/to/file - reads flag value from the given absolute filepath
2) -metricsAuthKey=file://./relative/path/to/file - reads flag value from the given relative filepath
3) -metricsAuthKey=http://some-host/some/path?query_arg=abc - reads flag value from the given url
The flag value is automatically updated when the file contents changes.
New labels `reason="wrong basic auth creds"` and `reason="wrong auth key"` were
added to metric `vm_http_request_errors_total` to help identify auth errors.

(cherry picked from commit 0638bbe69c)
support `Strict-Transport-Security`, `Content-Security-Policy` and `X-Frame-Options`
HTTP headers in all VictoriaMetrics components.
The values for headers can be specified by users via the following flags:
`-http.header.hsts`, `-http.header.csp` and `-http.header.frameOptions`.

* docs: make `httpAuth.*` flags description less ambiguous
Currently, it may confuse users whether `httpAuth.*` flags are used by HTTP client or server configuration(see https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4586 for example).

* lib/httpserver: introduce `-http.maxConcurrentRequests` command-line flag
Introduce `-http.maxConcurrentRequests` command-line flag to protect
VM components from resource exhaustion during unexpected spikes of HTTP requests.
By default, the new flag's value is set to 0 which means no limits are applied.

This handler will instruct search engines that indexing is not allowed for the content exposed to the internet. This should help to address issues like #4128 when instances are exposed to the internet without authentication.
- Call httpserver.GetQuotedRemoteAddr() and httpserver.GetRequestURI() only when the error occurs.
This saves CPU time on fast path when there are no parsing errors.
- Create a helper function - httpserver.LogError() - for logging the error with the request uri and remote addr context.

Incorrect 301 redirects can be cached by user agents such as web browsers.
This can complicate recovery procedure after the incorrect redirect is fixed,
e.g. web browser cache must be reset.
