Support for Azure Keyvault

[JoaoBrandao]

Hi, It will be very useful and secure to have a dependency that allows us to connect our Quarkus Applications properties with Azure KeyVault to retrieve secrets.

The concept is very simple, just add a few properties to enable the extension to list all properties and select those that make a match with a specific placeholder.

Example:

password: ${APPLICATION_USER_PASSWORD:localpassword}

In Spring Cloud there is already an extension for that https://learn.microsoft.com/en-us/azure/developer/java/spring-framework/configure-spring-boot-starter-java-app-with-azure-key-vault but this only works for spring I guess.

@radcortez I think you've worked on this, don't you?

[radcortez]

Not the KeyVault. I did the Azure App Configuration.

I also had plans to implement the Key Vault support. I'll do it in the next few weeks.

@radcortez there is already a Key Vault extension in Camel, I thought you were involved in it. I'll try to migrate this extension as a high priority

there is already a Key Vault extension in Camel

That one is JVM-only - i.e. it has no proper tests.

[radcortez]

I looked, and it is the specific Camel component, so it is not integrated with Quarkus Config system. We should provide proper integration with it.
