Add inference endpoints management page

[saikatsarkar056]

Description

In this PR, we implemented a view for managing inference endpoints. The changes include the following items for both Serverless and Stack.

• A blank page will be displayed if no inference endpoints are available.
• A page displaying a list of inference endpoints. The user can view various details about each endpoint, such as the endpoint itself, the provider, and the type. The table supports pagination and sorting.
• Users can add a new inference endpoint using Elasticsearch models and third-party APIs, including Hugging Face, Cohere, and OpenAI.

To keep the changes in this PR manageable, the following items are out of scope but will be added in subsequent PRs

• Option to delete an inference endpoint
• Filtering and Search bar
• Information about allocations, thread.
• Icons for Provider
• Deployment status of underlying trained models

@saikatsarkar056 thats fine, but given that ES3 is deployed weekly this should be disabled until the feature is ready and has adequate test coverage.
