Suggestion services folder structure

[andreyvelich]

/kind feature

Currently, we store all suggestion <algorithm_name>_service.py files under /pkg/suggestion/v1alpha3 directory.

Is there are reason to have structure like that? For example, for Golang Algorithms we have to store service in the same package as other files for the algorithm (See comment: #1131 (comment)).

I think we can add <algorithm_name>_service.py files to appropriate algorithm folder.

For example, hyperopt_service.py to https://github.com/kubeflow/katib/tree/master/pkg/suggestion/v1alpha3/hyperopt.
What do you think @gaocegege @johnugeorge @c-bata ?

I agree with your opinion 👍

Furthermore I think we can move /pkg/suggestion/v1alpha3/bayesianoptimization/src to /pkg/suggestion/v1alpha3/bayesianoptimization.
