What this PR does / why we need it:

Initial Operator functionality. Adds ability to provision a feast registry w/ ephemeral sqlite file-based DB. Also adds key fields to the FeatureStore.status... including conditions, feastVersion, serviceUrls, clientConfigMap, phase, & applied spec. With this change the operator will create the following objects for each FeatureStore CR -

Registry Deployment
Registry Service
Client ConfigMap w/ feature_store.yaml configured for remote registry access
