The bootstrap action is not idempotent

When deploying a cloud with the foundation cloud engine (fce) an application step will run the bootstrap action of the landscape-server charm. This is necessary to automate and standardize a deployment.

Unfortunately, if we run the landscape application step again, it re-runs the bootstrap action which fails with the following error in the action output:

    Error code: DuplicateAccount

The full output: https://pastebin.ubuntu.com/p/Pbb9cdyJnh/

Would it be possible to rework the bootstrap action to detect if landscape has already been bootstrapped and return the API credentials instead of throwing an error?
