Some providers do not support ingress pathType: Prefix

[TJM]

Changes proposed in this PR:

• Make PathType a parameter so it can be overridden (for example on the latest GKE 1.19.10)

How I've tested this PR:
helm template with a test.yaml that enables ingress and has a test host
Also tried the "bats" test? (make)

How I expect reviewers to test this PR:
see above?

If you want to test overriding the value, it would be like

helm install consul . -f test.yaml

test.yaml:

ui:
  ingress:
    enabled: true
    pathType: ImplementationSpecific
    hosts:
      - host: foo.bar
        paths:
          - /

Checklist:

• Bats tests added
• CHANGELOG entry added (HashiCorp engineers only, community PRs should not add a changelog entry)

Fixes: #1011

PS: Thanks for the Docker image :)

I have to assume that the acceptance tests that failed are because I ran them, and don't have access to a protected enterprise license variable?

Looks like #1016 will fix this once it is merged :)
