Add OSDe2e test harness to certman operator

[YiqinZhang]

• Add the osde2e test harness and migrated tests from osde2e. This includes improvements to the tests to not depend on osde2e.
• Modified manager.Options to have no specified namespace and port.

$ make lint
...
main.go:1: : # github.com/openshift/certman-operator
./main.go:149:3: unknown field Namespace in struct literal of type manager.Options
./main.go:151:3: unknown field Port in struct literal of type manager.Options
./main.go:156:3: unknown field MetricsBindAddress in struct literal of type manager.Options
./main.go:164:11: options.Namespace undefined (type manager.Options has no field or method Namespace)
./main.go:165:28: undefined: cache.MultiNamespacedCacheBuilder (typecheck)
/*
make: *** [boilerplate/openshift/golang-osd-operator/standard.mk:186: go-check] Error 1

• Commented out the CertificateReques status assertion as it fails on controller-runtime v0.16.3.
  The test client does not update the status of the cert runtime object, likely due to the addition of the WithStatusSubresource() functionality..
