Additions to azurerm_key_vault

[tombuildsstuff]

Adding the missing fields:

• application_id
• certificate_permissions

Also added application_id to the azurerm_client_config data source as it was needed

LGTM, assuming all relevant acceptance tests are passing.

Wondering if there's an array/slice of all permissions, so that we don't need to update this list after Azure introduces new ones. 🤔

[tombuildsstuff]

it's exposed as a collection of Constants, so it might be hard in the short term - however we could ask the SDK team to expose that as a function?

Up to you, it's no big deal - I just thought it may save us some pain/work in the future.
Feel free to 🚢 it as is.
