Use Patch instead of Update for HostedCluster Objects

[davidvossel]

The HypershiftAddonOperator is using an outdated version of the HostedCluster API. The result is when this controller performs an Update on a HC, some new fields get dropped that this controller has no knowledge of.

One way to prevent this moving forward is to always use a Patch operation on objects owned by other controllers (like the HostedCluster object).

Test API/Unit - Success
