test: fix otlp log integration tests failing with some set of features

[paullegranddc]

I like to run cargo test --workspace --all-features to run all tests in a workspace. This is currently failing:

• Running otlp logger integration tests with reqwest-blocking-client and the default features in the integration_test_runner package are failing two of the tests are not compatible with having both reqwest-blocking-client and tonic-client enabled at the same time.
• Running otlp logger integration tests with experimental_metadata_attributes fails because of the extra attributes added to logs do not match the snapshot.

Changes

• Skip tests on incompatible features
• Remove extra attributes before doing the snapshot comparison if the experimental_metadata_attributes flag is set

Merge requirement checklist

• CONTRIBUTING guidelines followed
• Unit tests added/updated (if applicable)
• Appropriate CHANGELOG.md files updated for non-trivial, user-facing changes
• Changes in public API reviewed (if applicable)
