create CDC event stream CRD (#1570)

Browse Source 
* provide event stream API
* check manifest settings for logical decoding before creating streams
* operator updates Postgres config and creates replication user
* name FES like the Postgres cluster
* add delete case and fix updating streams + update unit test
* check if fes CRD exists before syncing
* existing slot must use the same plugin
* make id and payload columns configurable
* sync streams only when they are defined in manifest
* introduce applicationId for separate stream CRDs
* add FES to RBAC in chart
* disable streams in chart
* switch to pgoutput plugin and let operator create publications
* reflect code review and additional refactoring
