Add open telemetry sample

Add open telemetry sample

Leaving as draft for two reasons:

• Due to some samples depending on an old server version I couldn't add newer otel SDKs so I temporarily removed them
• The unit test is not getting the correct spans and I suspect their is a bug with interceptors in the test enviorment

Hi, I have a similar problem with my PR: #296
That PR has been there for months but cannot be merged because of #293

[Quinn-With-Two-Ns]

@emanuelef Sorry I completely missed your PR or that it was blocked. I will create a PR to upgrade the server dependency.

@Quinn-With-Two-Ns I see as part of this PR some samples have been removed, did you need that to be able to use OpenTelemetry modules ? I might need to do the same in my PR, provided it makes sense to have both PRs been merged.

[Quinn-With-Two-Ns]

@emanuelef No samples should be removed, I just did that to unblock myself from dependency issues. It doesn't make sense to merge both out PRs. I am fine merging yours and I may make a follow up PR to add a few more cases to it to align it with our other SDKs otel examples

The imports where I'm having problems as well are:

In grpc-proxy and codec-server:
go.temporal.io/server/common/authorization
go.temporal.io/server/common/config

What would be the new way to import those modules ?

@Quinn-With-Two-Ns The PR #296 is ready to be merged

@emanuelef Thanks, sorry was out of the office.
