CSPL-4022 Remove pipeline config from inputs

[kasiakoziol]

Description

This PR simplifies the inputs for I&I separation. Instead of passing a lot of inputs to the IndexerCluster and IngestorCluster that are the same and are shared among them in a single cluster setup, the inputs are provided once to a BusConfiguration CR which can be then referenced by IndexerCluster and IngestorCluster . What is more, the number of inputs is decreased only to the ones that matter and are clear to the users (bus specific values). The rest of them is assigned fixed values.

Key Changes

• New CR: BusConfiguration
• Fixed values for pipeline configuration and some bus config inputs

Testing and Verification

• Automated tests
• Manual tests
