Extraktion S3-Buckethandling in api-base

Die Behandlung der S3-Dateien soll in das rdm/biome/api-base>-Projekt verschoben werden.

Im Zuge des Umzuges soll auch die Verwaltung der Dateien dokumentiert werden.

AK

• Behandlung von S3-Dateien ist in api-base-Projekt verschoben
• Dateihandhabung ist dokumentiert

• Dependencies and configuration is moved: composer dependencies (vich uploader, aws flysistem) and services definitions in config folder. Environment variables stay in the main project, these must be injected from the main project.
  • Note: it is not possible to remove vich and flysystem into the package, because that would require to have extensions dependencies between api-base and those 2 bundles. I do not currently know of the way to do so, so I left the vich and flysystem in top project and documented the services definitions in the readme.
• Services from Service/Media directory are moved into api-base package
• REST controllers are moved into the package (with routes)
• (optional) Handle 500 error on restricted file upload, when aws credentials are wrong
