Peer configuration management (#69)
* feature: add config properties to the SyncResponse of the management gRpc service

* fix: lint errors

* chore: modify management protocol according to the review notes

* fix: management proto fields sequence

* feature: add proper peer configuration to be synced

* chore: minor changes

* feature: finalize peer config management

* fix: lint errors

* feature: add management server config file

* refactor: extract hosts-config to a separate file

* refactor: review notes applied to correct file_store usage

* refactor: extract management service configuration to a file

* refactor: simplify management config
