Closes #120

Thanks for the contribution!
I'd encourage you to check in the retry handler which most likely has some of those headers as well.

[ev-gor]

I've searched the whole project for attributes listed in #121 and replaced them all. Retry handler has retry_count attribute mentioned in #119, but I wanted to create another PR for it, because I'm not sure about implementation of retry_delay attribute. "int duration in seconds before the request was retried" Does it mean number of seconds between every retry or total sum for all retries?

[baywet]

Thank you for the additional information.

The attributes in the retry handler are both outdated AND different from the fullfill/reject implementations...
We'd need to:

1. move them to a constant to avoid repetition
2. update them

The areas I could find

kiota-http-guzzle-php/src/Middleware/RetryHandler.php

Line 161 in 0fb71b6

$rejectedSpan->setAttribute('http.retry_count', $retries);

kiota-http-guzzle-php/src/Middleware/RetryHandler.php

Line 117 in 0fb71b6

$span->setAttribute('retryCount', $retries);

And to answer your question: retry delay I think it the delay of each retry (not the total delay).

Let us know if you have any additional comments or questions.

also the status code attribute is missing in this handler.

[ev-gor]

I added second commit to update resend_count and resend_delay attributes and add status_code attribute in RetryHandler class. If everything is ok, it closes #119

[baywet]

Thank you for making the changes!
Can you add a new changelog entry (patch bump, today's date, changed) please?
As well as align the version constant

This will ensure a swift release.

[ev-gor]

Done.
