Add pathType to Spryker webapp ingress

[Chemaclass]

Description

While upgrading our project to the latest harness, I faced this error:

spec.rules[0].http.paths[0].pathType: Required value: pathType must be specified, spec.rules[0].http.paths[1].pathType: Required value: pathType must be specified

After some research, I came to this post https://pet2cattle.com/2021/04/ingress-pathtype where it seems to be missing this property:

pathType: Prefix

The question that I have now is: which of the three possible options would be the optimised for this field?

We have tree options for selecting the pathType

• ImplementationSpecific: Matching will be handled by the IngressClass. Depending on the implementations can treat this in a different way
• Exact: Matches the URL path exactly with case sensitivity.
• Prefix: Matches based on a URL path prefix split by / (most common) It is also case sensitive on a path element by element basis.

Prefix is how we did the other ingresses https://github.com/inviqa/harness-base-php/pull/675/files
