Add a test to CATs to cover service binding parameters not being passed in

[sethboyles]

Context
Last week (March 24th) a PR was introduced to fix an issue where service binding parameters were not passed in on the apply manifest stage, this would mean that customers who pass in required parameters in as binding params would experience a break. We were asked by folks on the platform team to add a CATs test to cover this case.

Ask
Open a PR to CATs with a new test which makes sure that binding parameters are passed in on the apply manifest step (add the params to an app manifest, and validate they propagate to the broker on cf push)
