Update Harvester Helm chart to run and configure multiple workers for different workflows

[mario-winkler]

Description

The tasks of the Sentinel and Landsat workflows should be executed by individual worker processes (one worker per workflow). The Helm chart of the Harvester deployment should extended so that the multiple releases can be deployed in the same namespace. Additionally, a config file must be deployed.

Acceptance Criteria

• Multiple harvester worker instances can be deployed with differend release names e.g. registration-harvester-worker-landsat and registration-harvester-worker-sentinel.
• The config.yaml file is deployed as ConfigMap resource in the Harvester component.
