feat: CaraML SDK - v0

[maniteja6799]

Consolidating sdk from all Caraml apps.

As part of this PR, [TLDR]

• A new caraml-sdk is created with a specific skeleton structure.
• Workflows added that can clone and generate openapi code from caraml-dev/merlin, caraml-dev/turing repos.
• All wrapper code from the corresponding repos moved and restructured according to caraml-sdk.
• All unit tests from corresponding repos moved to this caraml-sdk/tests.

CaraML SDK Structure

All SDK code of corresponding CaraML apps will be moved to models/routers/store packages.
common package will have session, project, secrets related code. [Not in scope of this PR]

Generate and Sync Open API code from caraml-dev/merlin, caraml-dev/turing repos.

A new workflow (.github/workflows/caraml-sync-generated-client.yaml) to clone the repo and generate python client using openapi-generator-cli. This workflow accepts the following inputs :

      module:
        required: true
        description: "module name"
      repository:
        required: true
        description: "caraml app repo : `caraml-dev/merlin` or `caraml-dev/turing`"
      ref:
        required: true
        description: "the branch or tag to generate from"
        default: "main"
      openapi_generator_version:
        required: true
        description: "Open Api Generator cli version tag"
        default: v7.1.0
      openapi_schema:
        required: true
        description: "Open Api schema yaml file in the repo"
        default: "swagger.yaml"
      openapi_config:
        required: true
        description: "openapi generator config file"
        default: "openapi-sdk-codegen.yaml"   

!! NOTE: Turing needs to generate clients with v5.1.1 for now, Using the latest produces the client sdk with different format causing errors. This can be addressed later.

Turing wrapper code added to the PR. One test case failing, on first look, it seems to be an integration test which connects to turing server. Can be checked later.
