Macro otel_info

macro_rules! otel_info {
    (name: $name:expr $(,)?) => { ... };
    (name: $name:expr, $($key:ident = $value:expr),+ $(,)?) => { ... };
}

Note: These macros (otel_info!, otel_warn!, otel_debug!, and otel_error!) are intended to be used internally within OpenTelemetry code or for custom exporters, processors and other plugins. They are not designed for general application logging and should not be used for that purpose.

When running tests with --nocapture, these macros will print their output to stdout. This is useful for debugging test failures and understanding the flow of operations during testing.

Macro for logging informational messages in OpenTelemetry.

• Additional optional key-value pairs can be passed as attributes.
