Add status.installedBundleSource

[awgreene]

Introduce the status.installedBundleSource which should reflect the bundle image sha/git commit which can be derived from this structure in the RukPak bundle status.

A corresponding condition should exist which represents whether or not the operator is installed:

 Status:
  conditions:
    - type: "Installed"
       status: "False"
       reason: "PrettyBigBad"
       message: "The package does not exist"
       observedGeneration: 2

Related to #126, which references an Installed condition.
