Consolidate update/delete custom definitions to regular update/delete definitions

[xiaohansong]

FE should use the same API when user wants to update or delete their source or destination definition.

This ticket requires to consolidate 4 custom APIs into the original API (FE will use the one without custom in it, such as updateSourceDefinition)

Also as part of the effort we should remove the legacy creation path to avoid misuse:

POST /v1/source_definitions/create
POST /v1/destination_definitions/create

Refining notes:

• Before removing any routes, we should check to see if there are other places that call them. For instance, does Octavia CLI call POST /v1/source_definitions/create or POST /v1/destination_definitions/create? @alafanechere perhaps you know the answer to this?

I was doing a PR to implement custom definitions, so as far as I know, octavia do not call it yet. My implementation is using the endpoints with the "custom" prefix
