Breaking changes since 0.3.1

Configuration:

Feature system

Introduced feature system, which is controlled by _features.conf.

Database (waltid-wallet-api)

Unified db.sqlite.conf, db.postgres.conf, db.mssql.conf, db.conf (referencing either of the first 3) to just db.conf
- remove your db.conf (which only contains the link to any of the other config files)
- rename your db.sqlite.conf/db.postgres.conf/db.mssql.conf (whichever you actively use) to db.conf
- rename hikariDataSource to dataSource

OCI integration (waltid-wallet-api)

wallet-api: Moved functionality of individual oci.conf / oci-rest-api.conf to key-generation-defaults.conf
TODO: Test this

OIDC (waltid-wallet-api)

Moved publicBaseUrl from web.conf to oidc.conf -> now only required to be set when OIDC login is used

Credential issuance metadata (waltid-issuer-api)

Massively simplified credential-issuer-metadata.conf configuration structure for supportedCredentialTypes

(Non-breaking) No longer needed configurations (waltid-wallet-api)

You can remove the no longer needed files:
- wallet.conf (was remote-wallet-configuration)
- marketplace.conf
- chainexplorer.conf
You can remove the no longer needed attributes:
- enableOidcLogin from oidc.conf (now handled as feature switch)
