[CP-371] Updater miscelanous developer mode and logs changes

Changed:
- Runtime disabled logs which didn't add value from ServiceDesktop
- Runtime disabled logs which didn't add value from SystemManager
- Added possibility to change runtime logging levels
- Integrated ServiceDesktop developer code a bit - it might be used
  as virtual base with little to no modifications for other endpoints
  which would result with less redundant code
