[WIP] sync dashboard

[eelcovdw]

Description

• localstate now logs both state after successful sync, and status info on both success and error.
  • TODO log rejected files (no permissions, etc) with a rejected status, error status should be for connection/server errors
• local state now logs ignored files
• remove localstate init from consumer and add to manager. This way, producer has access to localstate too
• move producer logic from manager to new SyncProducer
• move common sync types to types.py to avoid circular imports
  • TODO cleanup enums with the same function in types.py
• change errorhandling in consumer so we can log failures to localstate
