Implement mechanism for copying types related to provider specific config from Gardener

[akgalwas]

Description

In the current implementation of AWS, GCP, and OpenStack provider specific config is directly using dependencies to Gardener repositories. For Azure the provider specific config uses type that is copied from the Provisioner. We need to have consistent solution.

Idea:

• we can fetch the types from the Gardener repos to the KIM's source code at build time

Reasons
There is a problem with direct use of the Azure Gardener Extension's dependency. It requires client-go version that conflicts with requirements defined in Infrastructure Provider's go.mod. The only way would be to fix Azure Gardener Extension's go.mod that seems to be not feasible.
