Please allow use of existing AppProjects if available

[RickJWagner]

Feature Suggestion

Every time the backstage ArgoCD plugin is invoked it must create a new ArgoCD "AppProject".

This goes against how many (most?) organizations build out their Argo CD architecture. An "AppProject" often is used as a way to logically organize groups of Argo CD "Applications". However, it is rare that all of these "Applications" are created at the exact same time.

The plugin should be able to take an existing "AppProject" name as a parameter and simply use this if it already exists, and only create a new "AppProject" if it doesn't.

Possible Implementation

N/A

Context

We'd like to be able to use the plugin, but not have a new AppProject every time it runs.

Thank you!
