and one more question, in the values, I also see the values for the default tokens:

credentials: apiserver: # -- Set for apiserver_key field accessKey: "5442F3443MJMORWZA3ZH" # -- Set for apiserver_secret field secretKey: "BxapIRo9ZINi8x25CRxz8Wdmr2pQjzuWVB4PNASZqCtTyWgWVQ" tests: # -- Set for tests_user_key field accessKey: "ENP39EQM4SLACGD5FXB7" # -- Set for tests_user_secret field secretKey: "lPcm0imbcBZ8mwgO7tpadutiS3gnJD05x9j7afwXPS35IKbpiQ"what kind of token are they? shall I produce them with some specific procedures, or they are just random strings?

Also is it the same if I provide them as environment variable? It would be better to us so that we don't have to store them in some places
