Extend HTTP API with Account endpoints to configure global peer login expiration.
GET /api/accounts
PUT /api/account/{id}/
The GET endpoint returns an array of accounts with
always one account in the list. No exceptions.
The PUT endpoint updates account settings:
PeerLoginExpiration and PeerLoginExpirationEnabled.
PeerLoginExpiration is a duration in seconds after which peers' logins will expire.
This PR adds system activity tracking.
The management service records events like
add/remove peer, group, rule, route, etc.
The activity events are stored in the SQLite event store
and can be queried by the HTTP API.
