Change Management Sync protocol to support incremental (serial) network changes (#191)

* feature: introduce NetworkMap to the management protocol with a Serial ID

* test: add Management Sync method protocol test

* test: add Management Sync method NetworkMap field check [FAILING]

* test: add Management Sync method NetworkMap field check [FAILING]

* feature: fill NetworkMap property to when Deleting peer

* feature: fill NetworkMap in the Sync protocol

* test: code review mentions - GeneratePrivateKey() in the test

* fix: wiretrustee client use wireguard GeneratePrivateKey() instead of GenerateKey()

* test: add NetworkMap test

* fix: management_proto test remove store.json on test finish
