misc: expose reusable logging functions

[hgiasac]

This pull request refactors how loggers are created, injected, and retrieved from context throughout the connector codebase. The changes centralize logger context handling, improve logger initialization, and enhance request ID generation for better traceability. Key updates include removing duplicated logger code, introducing helper functions for context and logger creation, and improving how request IDs are determined.

Logger context management and initialization:

• Introduced NewContextLogger and NewJSONLogger helper functions in logger.go to standardize logger creation and context injection, replacing custom logic and removing the old initLogger function. (F055989eL15R15, F055989eL155R155, [[1]](https://github.com/hasura/ndc-sdk-go/pull/207/files#diff-e11f4a70ce3453d64ce4799174ff9740fde5fd7fa03b9ebee3116adf80819e70L71-R75), [[2]](https://github.com/hasura/ndc-sdk-go/pull/207/files#diff-e11f4a70ce3453d64ce4799174ff9740fde5fd7fa03b9ebee3116adf80819e70L92-L112))
• Replaced all usages of the previous logContextKey and direct context manipulation with the new loggerContextKey and NewContextLogger for consistent logger propagation. (F055989eL146R146, [connector/server.goL130-R130](https://github.com/hasura/ndc-sdk-go/pull/207/files#diff-83302262c5bae5edff30c79b5c66523a44fbf1435e957341aab5a68306140546L130-R130), F823ecd0L232R232)

Request ID and tracing improvements:

• Enhanced the getRequestID function to prefer the HTTP header, then use the trace ID from the OpenTelemetry span, and finally fall back to a generated UUID, improving request traceability. (F823ecd0L321R321, F823ecd0L112R112)

Code cleanup and dependency management:

• Removed unused imports (os, strings, and context) from files now using centralized logger helpers. ([[1]](https://github.com/hasura/ndc-sdk-go/pull/207/files#diff-e11f4a70ce3453d64ce4799174ff9740fde5fd7fa03b9ebee3116adf80819e70L7-L8), [[2]](https://github.com/hasura/ndc-sdk-go/pull/207/files#diff-7456e9f6044d6088e014ed4672d950d8d0d4bf054e8be927eb6ec76aef1c44feL5))
• Removed the obsolete serverContextKey and logContextKey definitions from http.go. (F823ecd0L23R23)

Minor telemetry improvement:

• Updated resource attribute gathering in telemetry setup to include environment attributes for more complete OpenTelemetry resource information. ([[1]](https://github.com/hasura/ndc-sdk-go/pull/207/files#diff-5a289d8977f52b8f78b3c6e86385a4b6544a07440f869c477d5f49ddece84bdcL379-R380), [[2]](https://github.com/hasura/ndc-sdk-go/pull/207/files#diff-5a289d8977f52b8f78b3c6e86385a4b6544a07440f869c477d5f49ddece84bdcR389-R390))
