[RULE] Use a dedicated path for container app http health probes

[BernieWhite]

Existing rule

No response

Suggested rule

This rule is similar to #3111, however in this rule we are only checking existing health probes if they have been configured. If the health probes have not been configured then this rule passes.

If a health probe of type httpGet is configured it must set a path that is not / i.e. the root of the application.

Pillar

None
