OpenShift Route support

[case0sh]

oCIS 6 supports OpenShift Route configurations . The chart support for this feature should be added within this issue.

Just adding the comment here. Currently there is some investigation whether include support or just add documentation. Test of possible documentation currently outstanding, afterwards we will change the README.md to add those descriptions.

From what I remember, we'll not gonna add routes to the oCIS chart. They can be included via

ocis-charts/charts/ocis/values.yaml

Lines 845 to 847 in c6ef3d2

	# Include arbitrary resources, eg. config maps or a cert-manager issuer (see example below)
	# -- Extra resources to be included.
	extraResources: []
