Encryption schema is being loaded multiple times

[d-klotz]

The encryption schema is currently being loaded multiple time during the lambda invocation. Ideally this schema should be loaded once and then re-used by the methods that need it.

Currently it is initialized in the documentdb-encryption-service.js via loadCustomEncryptionSchema() and in prisma.js also via loadCustomEncryptionSchema()
