Story (Required)

As a QE I want to run basic tests for HTTP resolver with every new build in multiple configurations.

Background (Required)

HTTP resolver docs https://tekton.dev/docs/pipelines/http-resolver/ 

Approach (Required)

Create basic tests for HTTP resolver similarly to how we test bundle resolver, hub resolver, git resolver and cluster resolver in https://github.com/openshift-pipelines/release-tests/tree/master/specs/pipelines
