fix: analyze command default backend bug

[VaibhavMalik4187]

Closes #902

📑 Description

Now, the default value of the backend flag for the analyze command will be an empty string. The NewAnalysis function has been modified to use the default backend set by the user if the backend flag is not provided and the defaultprovider is set in the config file. Otherwise, the backend will be set to "openai".

This looks like it's just moving the functionality elsewhere?

This looks like it's just moving the functionality elsewhere?

Consider the following scenario if this fix was not present:

1. I set the default provider to say localai
2. Suppose, I've also configured an "openai" backend and instead of using the default provider, I want to use openai to analyze the cluster.
3. How would I do that by specifying the backend flag? These conditions would enter the following if block and force set the backend to localai:

if configAI.DefaultProvider != "" && backend == "openai" {

However, using the fix I proposed, the user can also specify openai as the backend for the analyze command. And setting the default value of the backend flag as "" helps in identifying if the user wanted to openai or not.

I think you hunch is right, this is a separate problem because I saw changes related to cmd/serve/serve.go when rebasing #929 on main. I'll look into it and open a PR with the fix.

No worries, I've rebased the PR to include the latest changes on main.
