Libs package

**Description**
Some helper classes are defined in each backend service (i.e. s3-integration-service, backend-template).
These classes that are never changed should be extracted to new refarch-libs package.
It is important to ensure a practical division of the classes into different packages.

At least following classes are relevant:
- `configuration.nfcconverter.*`
- `configuration.UnicodeConfiguration`
- `configuration.JwtUserInfoAuthenticationConverter`
- `configuration.UserInfoAuthoritiesServices`
- `security.AuthUtils`
- `security.RequestResponseLoggingFilter`

While extracting this classes correct setup of properties needs to be implemented (i.e. properties class for RequestResponseLoggingFilter)
