[Enhancement] Support for other Ingress (Controller)

[Ragin-LundF]

What is the problem?

Actually it is only possible to deploy nginx-ingress-controller.

Solution requirements

• Configuration which Helm Chart for the ingress controller should be used (e.g. gloo/gloo) and its repositories (e.g. https://storage.googleapis.com/solo-public-helm) and credentials if it is a private repository
• Definition of the name of the values file for custom settings
• It must be possible to add multiple solutions
• For the project creation, there must be a selection which one should be used
