Loading Azure VM list takes really long time

[dharapvj]

What happened

When we try to create a new MD for a usercluster with provider = Azure, the VM list loading takes really long time. Almost 3 minutes!!

We should ideally pre-cache this list for really long time and also update this cached entry in background so that user experience is always smooth.

Some screenshots.

Expected behavior

VM sizes dropdown should be ready in less than 5 seconds

How to reproduce

Try to create a user-cluster with Azure as the provider.
On the screen to add Machine deployment - observe the time taken to populate VM sizes.

Environment

• UI Version: KKP 2.25.6
• API Version: KKP 2.25.6
• Domain:
• Others:

Current workaround

No workaround. I wait for 3 minutes to populate the list.
