sendRequest logs vague and misleading error messages

[kalinkrustev]

central-services-shared function sendRequest logs vague and misleading error messages (“Failed to send HTTP request to host“) with no details:

• no stack is reported
• URL and method could be useful to include
• it mentions HTTP, while it could be HTTPS
• it says “failed to send” but actually in many cases it did not fail to send, but in fact received an error response after successfully sending the request
