[Single-Step-Registration] Modify registrationRequest generation (CPI)

[WojSad]

If Active Mode Controller sees that there is a radio in the db needing single-step registration with digital_signature it will do the following:

• The radio can be of type A or B but needs indoor_deployment=true. If so, generate a registrationRequest for the radio with digitalSignature. Do not include installationParam in plain text.
• if the radio doesn't have indoor_deployment=true, log an error and do not generate the request (or handle this situation differently).
