Description

Supports additional ofc dashboard configuration fields added in https://github.com/openfaas/openfaas-cloud/pull/706

How Has This Been Tested?

Followed ofc-bootstrap user guide using these changes along with this patch to install ofc on k3s. Ran each of the following once with scm as github and again as gitlab:

ofc-bootstrap apply --file init.yaml
ofc-bootstrap apply --file init.yaml  --skip-sealedsecrets

The deployed dashboard includes the correct icons and links based on the configuration
