Create Preview Environment pointing to any branch

Right now Preview Environments can only be triggered when the PR is to the branch of the service on the Blueprint environment.

Example: app1 -> development, app2 -> master, app3 -> development.

• If I create a PR in app1 from feature -> development it will let me create a Preview Environment.

• If I create a PR in app1 from feature -> master it will not let me create a Preview Environment.

Both cases it will have app1 with the branch feature for the Preview Environment and the rest as they are configured. It does not really matter where the PR is pointing to, the branch from where the PR was created is what it needs to be tested.
