This PR adds operator interface to probe pkg

4836, I tried to add fuzz test for probe handler.

However, the current architecture made it impossible to mock probe operations, so I added probe operator interface.

This picture is about probe pkg.

Special notes for your reviewer:

I need feedback on the approach of passing probeOperator as a parameter to functions.

For example, the function GenerateExperimentManifestWithProbes in chaoscenter/graphql/server/pkg/probe/utils/utils.go directly accesses probe operation. I have added the probeOperator dependency to the handler that uses GenerateExperimentManifestWithProbes and updated the function calls to pass probeOperator as a parameter.
