Create installation yaml for operator-controller

[dtfranz]

Each component of OLM v1 should be installed through a consistent format. RukPak, for instance, is currently installed using a single downloadable yaml file (here). We should create a similar if not identical installation method for the operator-controller. If we choose to go another route, an additional issue must be created to do the same for RukPak (and probably cert-manager too).

Acceptance criteria:

• operator-controller can be installed from a single downloadable yaml file.

Note that the output of this issue should not install dependencies such as RukPak itself, just as RukPak does not install its dependencies through the same yaml. This should be taken care of in the next issue: #110 Also note that installing the operator-controller on its own through this yaml without installing the dependencies will not result in a successful installation. This information should be easily available so that users don't install this yaml only hoping for a successful OLM V1 installation. We should also have links to documentation for #110 available.

Possible idea: Install operator-controller via BundleDeployment
