app/vmauth: change response code when all backend are not available (#6676)
### Describe Your Changes

Change response code to 502 to align it with behaviour of other existing
reverse proxies. Currently, the following reverse proxies will return
502 in case an upstream is not available: nginx, traefik, caddy, apache.

app/vmauth: properly proxy requests to backend paths ending with /
Previously the traling / was incorrectly removed when proxying requests from http://vmauth/

While at it, add more tests for requestHandler()

app/vmauth: properly proxy HTTP requests without body
The Request.Body for requests without body can be nil. This could break readTrackingBody.Read() logic,
which could incorrectly return "cannot read data after closing the reader" error in this case.
Fix this by initializing the readTrackingBody.r with zeroReader.

While at it, properly set Host header if it is specified in 'headers' section.
It must be set net/http.Request.Host instead of net/http.Request.Header.Set(),
since the net/http.Client overwrites the Host header with the value from req.Host
before sending the request.

While at it, add tests for requestHandler(). Additional tests for various requestHandler() cases
will be added in future commits.

Revert "app/vmauth: reader pool to reduce gc & mem alloc (#6533)"
This reverts commit 4d66e042e3.

Reasons for revert:

- The commit makes unrelated invalid changes to docs/CHANGELOG.md
- The changes at app/vmauth/main.go are too complex. It is better splitting them into two parts:
  - pooling readTrackingBody struct for reducing pressure on GC
  - avoiding to use readTrackingBody when -maxRequestBodySizeToRetry command-line flag is set to 0

Let's make this in the follow-up commits!
