Model Handlers for Code Suggestion endpoint

Overview

Create 2 model handlers for the one endpoint with the intent set to generation for gitlab-code-generation and completion for gitlab-code-completion

Proposal

We need 2 model handlers for calling code-suggestions api, one for the code-creation pipeline, the other for the code-suggestions pipeline.

• Move code-creation pipeline under code-suggestions. We should have 2 subcommand in our cli
  • promptlib code-suggestions generation, this subcommand contains all the stuff in the current code-suggestions.
  • promptlib code-suggestions completion, this subcommand is the current code-creation pipeline.
• Add a new model handlers for code-suggestions API, which will be used by promptlib code-suggestions generation
