Redisotel: tracing Filter with ctx

[Udhayarajan]

This PR has one of the approach mentioned in #3760. With ability to propagate all the params we got in Dial, Process, Pipeline hook.

Making it fully flexible for filtering the trace.

Note

Low Risk
Low risk: changes are localized to redis OpenTelemetry hook filtering and are backward-compatible via deprecated wrapper options, with updated/expanded tests covering the new behavior.

Overview
Adds context-aware filtering to redis OpenTelemetry tracing by changing filterDial, filterProcess, and filterProcessPipeline to accept context.Context, and wiring that context through DialHook, ProcessHook, and ProcessPipelineHook.

Introduces new options WithDialFilterCtx, WithCommandFilterCtx, and WithCommandsFilterCtx, while deprecating the old WithDialFilter, WithCommandFilter, and WithCommandsFilter via wrappers; tests are renamed/updated and new cases verify filtering decisions based on values stored in context.
