Extension point for credentials types

[timja]

What feature do you want to see added?

Credentials providers types are currently hardcoded in the plugin, it should be an extension point so other plugins can contribute adapters:
https://github.com/jenkinsci/azure-keyvault-plugin#azure-key-vault-credentials-provider

azure-keyvault-plugin/src/main/java/org/jenkinsci/plugins/azurekeyvaultplugin/AzureCredentialsProvider.java

Lines 132 to 160 in a60991a
