Implement profiling for Rust using flamegraph-rs/flamegraph

[josepdcs]

Support for profiling Rust projects should be implemented in kubectl-prof, using the flamegraph-rs/flamegraph tool. This integration will allow the generation of execution flamegraphs for Rust applications, improving visibility into resource usage and bottlenecks.

Suggested tasks:

• Research how to integrate flamegraph-rs/flamegraph with the kubectl-prof workflow.
• Implement the necessary hooks to launch the profiler from kubectl-prof in Rust workloads.
• Document the use of this functionality in the project documentation.
