update quoteservice to opentelemetry-php beta

[brettmc]

Changes

• update to opentelemetry-php beta versions
• import only required opentelemetry-php libraries
• use php auto-instrumentation (remove most manual instrumentation, leaving enough to illustrate that auto+manual can work together)
• bump php to 8.2, the most recent version supported by opentelemetry-php

This looks great @brettmc, thanks for that!

I've tested it locally and it seems that we have some issues though.
After building this quoteservice I've started getting the following:

Could you take a look?

[julianocosta89]

I've built it in my Ubuntu and it worked.
Not sure what happened on Windows, but it LGTM!

[julianocosta89]

Just adding a screenshot here for visibility:

With this change quoteservice produces 14 spans per request.

Lgtm. Merging.

Thanks @brettmc for the contribution! 🦞

[cartersocha]

And @bobstrecansky for taking time to help with the review 😎

[puckpuck]

took me a while to test this one out, but I also see the same as @julianocosta89 did. The quoteservice now produces several auto-instrumented spans, well beyond what should be expected.

@brettmc can you please take a look at this? I'm going to open an issue as well.
